II have been using my CHA F Mag Loop for over 4 years now as my main antenna. It is set up indoors in my dinning room and hooked to my FT- 817nd 5 watt max. QRP rig. I use the solid aluminum big loop most of the time on 60 through 10 meters. CW is my main interest but I use SSB and PSK31 and JS8call some of the time also. I am on it every day either indoors or for my POTA activations in the field here in S. W. Utah.. I am a long time QRPer and even get down in the milliwatt output range. I must say, I have never had so much fun with the challenge of QRP as I have with this loop. One thing that was not mentioned is how by directional this antenna is even when operating from indoors This is a very directional antenna and it brings other stations out of the mud or can null unwanted interference noise. I’m anxiously waiting for 10 meters to open up. De WA6YPE 73
If you're limited on space, live in an HOA, or an apartment Magloops are a godsend! I use my AL 705 with my IC705 inside my Apartment on the ground floor and it works great!
After 60 years in ham radio I could On my extended lot in Florida.-- On my 70 foot crank up tower were the strong 15 foot mask going upward above, I had 3 high Gain yagis five elements on 20 ,15 meters had five elements and so did the 10m yagi. On a 70 foot tower separately I had a full size 40m two element quad with 30 meters wrapped inside two elements and then three elements on the 2 other warc bands. I had a 50 foot tower with various to meter gang Yagi. For 80 meters I installed two high gain high towers 130 feet apart and use the matching network which from the shack I could switch either bip or bop--- with part of that antenna on Japan or the other part on Europe switchable from inside the shack. All operated with everything from 800 to a kW output. Now I'm tuning into youtubes and seeing single element loop type antennas there are useful for portable or for using that condemnable FT8. And since I moved away from most of those other antennas I still have the Christmas tree but I realized looking at TH-cam that FT8 and the simple loop type antenna, low power, is saving him radio for all the hams that are penalizes from putting up big antennas and from running a kilowatt amplifier. So I guess FT8 and these little loops are saving ham radio and for that I say thank goodness.
I own the Cirro Mazzoni midi loop.. its quite an amazing antenna for its size 2M.. my first contact on 40M was Melbourne Australia with just 50 watts!!
Great video as always. I'm limited on space AND live in an HOA in Hawaii, but unlike comments below, no success. Running a Yaesu FT-891 and did the "no look" tuning @14:10. Good SWR, heard VE7TBN and ZL3XZ, but no contact.

Just building a mag loop with a Pi4 to drive a stepper motor coupled to the tuning capacitor. Currently working on the GUI in Python with memory and scanning options.
Very cool. I started writing my own, but then just went and bought a Wi-fi Stepper WSX100 board :-) Currently, going to try a normal DC motor with a high gear ratio to get better tuning as the capacitor I chose is hard to finely tune.
@@Ardren Yes, I'm using a stepper with 4:1 gearing which will turn the capacitor in 1/3 degree steps. Hopefully, that will be sufficiently fine enough control...
Great video, possibly the most complete (and steady-paced) step-by-step video on this loop that I've seen to date. *** Most of my use is with the loop indoors (HOA) I run the coax from the loop into an A/B switch box with "A" going to the rig and "B" to a antenna analyzer, which I put at the base of my tripod. This configuration allows me to adjust the loop while looking down at the analyzer. Once I get the best SWR I just switch to "A" and I'm ready to transmit. *** Recently I replaced my main station (TS-2000) with an Icom 7300 and I discovered that I could get very close to the correct SWR zone by watching the 7300's spectrum scope (it looks like a 'wave', which gets larger as the capacitor is tuned to the correct frequency. Too much one way or the other (right or left turn) and the wave decreases moving off to one side of the frequency or the other.. My hearing isn't as good as it used to be, so the visual indication on 7300 really helps (I imagine the 705 would be the same) *** Nice bag. I wish they (Chameleon) was more consistent with the bag they send out though (the F-Loop I bought this Spring came with a tiny 14" x 9" bag that barely allows everything to fit in it). *** What I'd really like to see as a followup video is where you test the loop with the CHA POWER COMPENSATOR (which I believe is just a door knob capacitor) and verify once and for all that it really gives you a good increase in the radiated power output (i.e.- "I talked to Bob and he said I'm 5/6 but when I added the Compensator it jumped to 5/9"). I've never seen a video where someone actually does an A/B test between stock loop and loop w/compensator doing a real world test like that. When someone DOES do a video with the Compensator it's never clear if it deflects most of the higher watts coming from the rig (with only a minimal increase coming out of the loop), or if the loop really uses everything the transceiver is putting out? 🤔 *** With the aluminum loop connected was your frequency spread the same (40-10) as with the coax, or did you loose a band at one end or the other? Also, was the bandwidth you saw the same as or better than with the standard coaxial loop? With the "booster" cable installed did you see a larger bandwidth on 40 or 20 meters, or was it just as narrow as with the stock loop? *** Once again: Great video....👍
I have both the F Loop with RTRR and a P Loop 2.0… Both are great! I agree with you, Josh… I am very impressed by the build quality of Chameleon. Just took delivery yesterday of Wolf River Coils antenna and expect to have a Chameleon MPAS 2.0 antenna system next week. I plan on being out standing in my field running some antenna comparisons with my amazing, fantastic ICOM 705! Yeah, I love mine too! 73 de Robert K3RRR
Hey Josh yeah I'm just getting back in the radio again I was bored for a long time but trying to check out antennas I just don't feel like building one I like to just buy one and put it up but that definite looks impressive I'm just watching the video now and I'll give you my opinion in another comment after it's over it looks pretty interesting thanks for sharing it 👍
Great summary! I need to get out more with mine to get better accustomed to using it, my only gripe being that it can be really finicky when it comes to getting the tuning knob just right. The high-power adaptor actually lists max output on SSB as 60W and I have had no problem pushing out at least 50W. I would think that at least on the higher bands that it will probably outperform most compromise antennas on 100W output and would rate it as more than simply a QRP setup.
All I can say is wow. That is an awesome portable antenna. Well done on the review showing the options and hands on assembly!!! Thank you!! I may have to get one of these down the road!!!
magnetic loops have been there for ages. They are a decent compromise for those who do not have the possibility to set up a larger antenna. While efficiency is marginal, for receiving they provide good directivity and thus good S/N. On transmitting any vertical will greatly outperform a loop. Magnetic loops are very easy and very cheap to build. With a fraction of what the Chameleon costs you build one as good as this and with a motor, which let you tune it remotely. Ham radio operators used to learn how to build the basic stuff they needed. Nowadays ham radio's main equipment seems to be the credit card!
As Always, thanks for your well done and informative videos. You have a very natural presence in front of the video camera. I have the F-Loop too, but with the two part metal out loop. It works well. I do agree with those who believe that SSB test are better. After all, who talks on FT8 (no talking) or on WSPR (also no talking). I once hit Antarctica with WSPR, but I was not able work work them a second later on SSB. I tried. So WSPR propagation say nothing about SSB propagation. Also if 'it WSPR goes out further' then again that's proof that SSB does not coincide with WSPR. WSPR is more fun than that dreaded ft8, which I can't pretend hard enough is radio. Again, thanks for the video. 73 from N2LRB
Thank you for the comment and kind words. The point of wspr is that you can see what paths are open, including SSB. It’s a fantastic mode for knowing when voice contacts are possible.
Chameleon Antennas are top notch and I have owned this loop antenna for a couple of years now. I went through a hate/love (yes in that order) relationship with it though. The portability and ease of setup (reliably 5min) is spectacular. BUT it’s useless on SSB Tx. Anybody claiming anything else is likely strongly biased. Still, SSB Rx isn’t actually too bad and it’s very quiet. You will find that reviewers of this antenna tend to focus on digital to demonstrate its performance. Well the reason is that’s it’s the only thing it’s useful for. Just don’t be fooled to believe you will have many SSB QSO’s. Even if you do make the occasional contact, it’s way too unreliable to be trusted when it really matters. I performed extensive testing in various settings and distances and can confirm that I’m usually not being heard on SSB, even if I hear the other station well. I use the power compensator btw so I can almost double the power (SSB 50W/ Digital 20W) I was never able to get 80m to work well other than some Rx and no longer bother to make it work. I think promoting it as a 80m antenna is a bit of a stretch. Interestingly, the power compensator doesn’t seem to work on 80m. This all sounds horrible, right? Well once I accepted that it’s basically useless on SSB I started loving it for what it is. The small package and 5min setup to Tx/Rx a couple of digital messages is actually pretty cool. It’s high quality too and a pure joy to own. Customer service and support is stellar - I’m a fan and own some of their other antennas. So there you have it, it’s a great antenna in its own right but you will hate it if you expect it to be a performer on SSB. As it had been mentioned earlier by someone else, any vertical will outperform it on SSB. Great video!
Interesting. I've worked DX on SSB with mine from AZ to South America and Europe with 10W. Is it easy...no, but I have made contacts. Conditions are getting better. Give it a try.
Nice review and I have one for some of my portable opps with my Kx2 where a full size antenna will not work of fit. I like the power compensator to use when I have more power.
I watched your video again to find out something. I was hoping you could tell me some thing. Your video was kind of long and I might’ve dozed off a couple of times, but is there’s a certain angle where you point the edge of the loop to get the best reception?
Very new and just exploring the ham radio hobby. I have a question. There seems to be 2 types (?) of communication styles? Active listening basically looks like actively tuning a bunch of static until you find a voice buried in static? Then Squelch listening where there are known channels that you stand by quietly until a transmission is made (CB,GMRS, FRS, 2m, 70cm?) This antenna is more designed for the static in voice style listening.
Might have to invest in one. Just got a IC-705 a couple of weeks ago and an end fed antenna to work HF with. Had some luck on 20m and 40m without using a tuner. Haven't done any weak digital signal modes yet, but plan on getting into trying some soon.
I bought a Cham V1 Vertical 10-80m for $299 back in 2008. When i called 2 years ago I was told all the stuff from CA was sold off and moved to NV. What sold me on it was the TH-cam vids. I made a contact from SE Idaho to Japan on 18 meters. His window was open just long enough and the band faded. After years of owning it i could no longer remember which end of the unun was antenna or coax side and called. The guy on the phone was surprise to find out there was still a V1 out there still working and said very few were and that in the move they lost all the documentation and the original website data had been lost. My only option is to take it apart and check it out. But i'm thinking of just tossing up 124.5 feet of wire and making a 9:1 unun and calling it a day. [edit] i sent to QRZ to get the link to the contact page and i found their members area seemed to be obliterated. Split up and sold off to 3rd party sites. And or took what they had and chopped it up calling parts of it standard and parts premium. Been a couple of years since i've been there.
Nice honest review you really can’t go wrong with a loop.... But l can’t believe the price there asking.... l know it’s great build quality.... they could at least thrown in a decent vacuum capacitor
I’m not familiar with whisper, I’m looking for a ham radio antenna that does voice communication, does this do that? I’m thinking of getting the Xaigu x6100
I truly love it chameleon made a really nice duffel bag to put the antenna in that makes the antenna even better that you could load it in that bag and carry it off to the country or to the woods and set up really love it man chameleon is number one I'm definitely going to buy that antenna
👍👍👍👍👍 Thanks for a very thorough walk-through! I am a total newbie. Just ordered my very first SDR Bundle kit from RTL-SDR Blog. May I ask: 1. Would this work with RTL-SDR Blog v3 to receive HF in Direct sampling Q mode? 2. Perhaps there is something else more suiting for indoor apartment use? Once again, thanks.
Nice video. Disappointed you didn't do the test with the 705. 😟 Definitely going to have a go at making a loop antenna. It seems expensive for what is mostly coax.
Top notch video as usual. Have you ever gotten a chance to test out any of the Ciro Mazonni loops. I'm looking to either put a transmitting loop in my attic or outside on my chimney about 20ft off the ground. Any recommendations for me would be greatly appreciated.
Great video! I'm looking into HF soon, and I've been eyeballing the Chameleon antennas. Would you please also consider reviewing the Chameleon MPAS antenna and comparing the two antennas? Thanks!
MPAS 2.0 is a great antenna, can handle 100 Watts and I've made several contacts from Ireland to South America on 20 Meters SSB @100 watts in the Summer 2020 in the Evenings and night UTC using just the single supplied counterpoise and the CAP HAT which I purchased separately. I do have a very low noise floor where I live too helping me hear lots of DX. It's also a fabulous SW receiving antenna, One thing that struck me is how quiet it is on receive compared to my wire antennas, I thought the Verticals were supposed to be noisier but the MPAS 2.0 is very quiet, again my area in the sticks is very quiet. The first night I set it up and heard a Brazilian station repeat my call, well, you can just imagine my face! I haven't used the wire antenna much but this would give much better performance on 160 and 80m but it still gets out well on FT8 on 80 and 160 on the vertical. It works so well I decided to leave it up all the time and take it down only for portable use, the exact opposite of what I bought it for but at least I'm making good use of it. I also have the excellent Super Antenna MP1, I even made a 1000 mile contact on 80m with the 80m Coil, but it can be a pain when band hopping going back and forth to adjust the coil, disconnecting the coax, hooking up to the analyser etc. The MPAS I can work several bands ( With the cap hat ) without a tuner. Get the MPAS 2.0, it can handle 100 Watts and it just works, every time.
@@o00scorpion00o I really appreciate your insight. Your comments confirm most of what I've heard/read regarding the MPAS 2.0. I live in the burbs, so I have space limitations that drive me towards verticles over wire dipoles. I'm running an ICOM 7300, so I'm thinking the MPAS would be a good fit for my needs along with the radio's internal tuner. Portability and field comms matter to me as well, so I much prefer a rig that can be quickly set up and taken down. My primary focus in HF is phone/voice contacts, but might look into the digital modes more closely next year when time permits. Good to know about the Super antenna. I looked at those as well and wasn't sure if all the adjusting/fiddling with it was worth it. Might take a second look. Thanks again!
That bag is about 5 times bigger than the original bag that the F Loop 2.0 came with. And that’s a good thing since thatLMR is so stiff it was a tight fit before to get all the stuff in the bag.
Thank you so much for doing a very nice edited video. (I hate live Premier shows and don't watch). I have the MFJ Magnetic Loop and to tell you the truth have not done much with it yet. Part of my problem is my XYL HOA. Castler stated is much be 20 feet off the ground. Therein lies the problem. To keep it out of sight I can only get it about five feet off the ground. Your video has spired me on to try again. Thanks for all you do.
I think Dave's height recommendation for the MFJ-1786 was for it mounted horizontally where it has similar requirements to a dipole or wire antenna. For it mounted vertically, the tribal knowledge says one loop diameter and excessive height above a ground plane can be detrimental. 73 de WG2H
Great Video! Thanks Josh, by the way with the help of your videos I got my basic w/honors here in Canada last weekend, your videos along with mike from K8MRD have really intrigued me and I'm quickly falling down the amateur radio hole haha. I look forward to the future live streams and maybe hearing from you on the air one day! 73 VE6JTW
@@HamRadioCrashCourse I was asking I suppose whether you have heard of that and agree that might work. Some propose making the inner loop more oval to increase the bandwidth of resonant frequency but moving it left or right?- not sure how that would work or what that would achieve unless it makes it more efficient for one band more than another?
Josh, I love your practical videos, but this time I have to be rather critical: There are very good reason that your viewers ask for SSB. I know it is convenient and easy to run Whisper and present a flashy chart - but it is meaningless without explantion: You told us that the SNR would reveal if the connection was actual useful for a SSB QSO - yet you only showed the map with the contacts - but not annotated with the SNR - so I am not a bit viser regarding range for SSB Also, you briefly showd an effectiveness chart and then quickly closed it withhout explanation of the significance of the numbers. Does the 13% effectiveness with the Boost option mean I only get an effective 1.3W in the air when transmitting with 10W on 40m ? I would love to see tests on SSB (!) with range and time of day included. Reason: I consider buying it - it is expensive - so I do not want to rely on sponsored videos only
Are you aware of any motors that you can use to turn these capacitor knobs universally fittable? If i have one in my loft I dont want to climb up to make every adjustment
Interesting vid Josh. Thankyou! I gave it a ‘like’. Couple of comments: 1. Is your outdoor chair metal? 2. Some discussion re. Health and Safety aspects due to potentially high currents present at (especially) LF with magloops eg your XYL goes outside to hang the washing out while you are leaving it to do WSPR and she touches the non-rubber-booted PL259 assemblies to move it; minimum recommended distance between loop and operating position as a function of frequency (to avoid a permanent headache!)? etc. 3. Is there a (future) remote mechanical tuning option eg with a cable drive or motor drive for the case when you want it outside (eg your rv) while you are cosy inside so as to avoid constantly running in and out. Thanks again, Nick M1DDD
Hey Josh. Tnx for another great video. I didn’t have much luck with loops inside a hotel room. Have you ever tried it? Did it work with the CHA loop? I really would appreciate your opinion about that. 73 de Rico, DG5BQ
@@HamRadioCrashCourse Well, some of the hotels do have one. But even if, they are quite narrow. I think the metal of the window or door frames behind the antenna would have negativ effects on the antenna. And I would only get have of it out while the other have would have to stay inside. So it’s just for the summertime 😉. But many thanks for the quick reply.
Nice system, but QRP should be emphasized since the operator needs to be within arm's length of the antenna, which makes it easy to exceed radiation exposure limits. That's when a remote auto-tuner really is a value.
Hi Steve, I bought this antenna from Radioworld in the UK (early November) and you get the bag if you order the total version. Not sure about the standard though.
I'm still waiting for Chameleon Antenna to build a "matcher" much like the "CHA-MIL Hybrid rated @500 watts" to handle a kilowatt - so, those of us working from an apartment with a balcony railing can run a decent amplifier on the lower HF bands. I REALLY just want to be able to transmit a solid 500 watts everywhere I can, because it make me feel whole and complete, (sarcastically speaking, lol). KD8EFQ/73 Good video.
@@HamRadioCrashCourse Would I need to do anything different to operate NVIS? How low to the ground do you recommend keeping the antenna for normal operation and for NVIS? Thanks! W2QLH 73
I've used mine, checking-in on an 80m net, with Net control being 45mi away, and several 20-30mi distance 10m contacts with ease, but band conditions will always play a part in my success (or lack of).
Well I was watching your video and the one thing that I didn't see you show was the aluminum loop it I'm assuming it's just one solid loop that you can't collapse it and put it into the backpack that's what I was looking forward to seeing but you never did anything it just cut to the very end here and you see the aluminum loop so it I'm assuming that it's just one solid piece that you can't collapse and put it in the backpack.
Great video and I'm sure the antenna works very well but I feel it's too fiddly and to much tuning, everytime you move you have to retune , I live in the uk and this is not going to get used for 5 months of the year with winter weather high winds and rain I wouldn't want to keep running outside to tune even on a pleasant day , lot of money for what cannot be made a permanent fixture outside and to big to leave up in the house
WSPR will only tell you how far/well your WSPR will go. It will not tell you a thing about SSB propaganda. Which is why I just go ahead and test on the mode I wish to use, mainly SSB. I do have and use my Chameleon F-Loop. It works like you said. I use it indoors in my bedroom for HF contacts. I also tried it in outdoors in New York City’s Central Park once and made some contacts. 73 de N2LRB.

All this stuff looks really fun. Must be nice to have a ham radio license. FCC is refusing to give me mine. I passed all three tests in April 2019. But FCC is keeping my FRN status "pending" because I checked the felony box. Yeah, I made a mistake in the past. I guess they're afraid I'm going to talk someone to death. At least I tried the legal route. I'm gonna start keying my ham radio down anyway with a fake call sign. Hey, I tried...
Guess you left out the very high Q on small loops at low Freq and the extremely low Bandwidth and huge phase shifts for SSB type signals that then sound terrible.
He literally says they are high Q and and have an extremely narrow bandwidth (when looking at and based on a representation of a typical SWR curve). What on earth are you talking about?
How can they be a resonant antenna? They're quite the opposite really, especially when considering they're designed to operate on such a broad frequency range in just one or two lengths. I'm a CBer and I know that (101 basics), like the rapper of that song. And you really shouldn't keep saying loop antennas, in reference to certain characteristics. The category of antennae is small loop. This is misleading for beginners when compared to an actual resonant loop.

Nice bag. I wish they (Chameleon) was more consistent with the bag they send out though (the F-Loop I bought this Spring came with a tiny 14" x 9" bag that barely allows everything to fit in it).
***
What I'd really like to see as a followup video is where you test the loop with the CHA POWER COMPENSATOR (which I believe is just a door knob capacitor) and verify once and for all that it really gives you a good increase in the radiated power output (i.e.- "I talked to Bob and he said I'm 5/6 but when I added the Compensator it jumped to 5/9"). I've never seen a video where someone actually does an A/B test between stock loop and loop w/compensator doing a real world test like that.
When someone DOES do a video with the Compensator it's never clear if it deflects most of the higher watts coming from the rig (with only a minimal increase coming out of the loop), or if the loop really uses everything the transceiver is putting out? 🤔
***
With the aluminum loop connected was your frequency spread the same (40-10) as with the coax, or did you loose a band at one end or the other?
Also, was the bandwidth you saw the same as or better than with the standard coaxial loop?
With the "booster" cable installed did you see a larger bandwidth on 40 or 20 meters, or was it just as narrow as with the stock loop?
***
Once again: Great video....👍
I have both the F Loop with RTRR and a P Loop 2.0… Both are great! I agree with you, Josh… I am very impressed by the build quality of Chameleon. Just took delivery yesterday of Wolf River Coils antenna and expect to have a Chameleon MPAS 2.0 antenna system next week. I plan on being out standing in my field running some antenna comparisons with my amazing, fantastic ICOM 705! Yeah, I love mine too!

Hey Josh yeah I'm just getting back in the radio again I was bored for a long time but trying to check out antennas I just don't feel like building one I like to just buy one and put it up but that definite looks impressive I'm just watching the video now and I'll give you my opinion in another comment after it's over it looks pretty interesting thanks for sharing it 👍
I'm not only getting back into the ham arena and I also decided to go with a loop hopefully I'll be able to figure it out.
Great summary! I need to get out more with mine to get better accustomed to using it, my only gripe being that it can be really finicky when it comes to getting the tuning knob just right. The high-power adaptor actually lists max output on SSB as 60W and I have had no problem pushing out at least 50W. I would think that at least on the higher bands that it will probably outperform most compromise antennas on 100W output and would rate it as more than simply a QRP setup.
All I can say is wow. That is an awesome portable antenna. Well done on the review showing the options and hands on assembly!!! Thank you!! I may have to get one of these down the road!!!
Good video. Haven’t watched in awhile and your channels has sure grown.
magnetic loops have been there for ages. They are a decent compromise for those who do not have the possibility to set up a larger antenna.
While efficiency is marginal, for receiving they provide good directivity and thus good S/N.
On transmitting any vertical will greatly outperform a loop.
Magnetic loops are very easy and very cheap to build. With a fraction of what the Chameleon costs you build one as good as this and with a motor, which let you tune it remotely.
Ham radio operators used to learn how to build the basic stuff they needed. Nowadays ham radio's main equipment seems to be the credit card!
As Always, thanks for your well done and informative videos. You have a very natural presence in front of the video camera. I have the F-Loop too, but with the two part metal out loop. It works well. I do agree with those who believe that SSB test are better. After all, who talks on FT8 (no talking) or on WSPR (also no talking).
I once hit Antarctica with WSPR, but I was not able work work them a second later on SSB. I tried. So WSPR propagation say nothing about SSB propagation. Also if 'it WSPR goes out further' then again that's proof that SSB does not coincide with WSPR. WSPR is more fun than that dreaded ft8, which I can't pretend hard enough is radio. Again, thanks for the video. 73 from N2LRB
Thank you for the comment and kind words. The point of wspr is that you can see what paths are open, including SSB. It’s a fantastic mode for knowing when voice contacts are possible.
Also, is it fair to compare the Super Antenna MP1DXTR80 to this one. Great video. You enjoy spending my money
Which one should I buy? That was going to be my question for this episode? Lol :)
Iv been using one for years, awesome loop
Chameleon Antennas are top notch and I have owned this loop antenna for a couple of years now. I went through a hate/love (yes in that order) relationship with it though. The portability and ease of setup (reliably 5min) is spectacular. BUT it’s useless on SSB Tx. Anybody claiming anything else is likely strongly biased. Still, SSB Rx isn’t actually too bad and it’s very quiet. You will find that reviewers of this antenna tend to focus on digital to demonstrate its performance. Well the reason is that’s it’s the only thing it’s useful for. Just don’t be fooled to believe you will have many SSB QSO’s. Even if you do make the occasional contact, it’s way too unreliable to be trusted when it really matters. I performed extensive testing in various settings and distances and can confirm that I’m usually not being heard on SSB, even if I hear the other station well. I use the power compensator btw so I can almost double the power (SSB 50W/ Digital 20W)
I was never able to get 80m to work well other than some Rx and no longer bother to make it work. I think promoting it as a 80m antenna is a bit of a stretch. Interestingly, the power compensator doesn’t seem to work on 80m. This all sounds horrible, right? Well once I accepted that it’s basically useless on SSB I started loving it for what it is. The small package and 5min setup to Tx/Rx a couple of digital messages is actually pretty cool. It’s high quality too and a pure joy to own. Customer service and support is stellar - I’m a fan and own some of their other antennas. So there you have it, it’s a great antenna in its own right but you will hate it if you expect it to be a performer on SSB. As it had been mentioned earlier by someone else, any vertical will outperform it on SSB. Great video!
Interesting. I've worked DX on SSB with mine from AZ to South America and Europe with 10W. Is it easy...no, but I have made contacts. Conditions are getting better. Give it a try.
I’ve been thinking about purchasing one of these. Thanks for the review!
Nice review and I have one for some of my portable opps with my Kx2 where a full size antenna will not work of fit. I like the power compensator to use when I have more power.
HEY ! Did you try it making the small loop more oval ?
I watched your video again to find out something. I was hoping you could tell me some thing. Your video was kind of long and I might’ve dozed off a couple of times, but is there’s a certain angle where you point the edge of the loop to get the best reception?
I just put my loop together. I like the idea of no ground plane or radials. First I need to wait for my radio to come in.
Sweet! I've been thinking about getting one! Perfect timing.
The big question, can this be used to DX on the AM broadcast band?
Very new and just exploring the ham radio hobby. I have a question. There seems to be 2 types (?) of communication styles? Active listening basically looks like actively tuning a bunch of static until you find a voice buried in static? Then Squelch listening where there are known channels that you stand by quietly until a transmission is made (CB,GMRS, FRS, 2m, 70cm?) This antenna is more designed for the static in voice style listening.
Might have to invest in one. Just got a IC-705 a couple of weeks ago and an end fed antenna to work HF with. Had some luck on 20m and 40m without using a tuner. Haven't done any weak digital signal modes yet, but plan on getting into trying some soon.
Great Video, Good Timing, Just bought a KX3, looks like a Loop is the way to go for Portable use, Great Winter Project 73's
I bought a Cham V1 Vertical 10-80m for $299 back in 2008. When i called 2 years ago I was told all the stuff from CA was sold off and moved to NV. What sold me on it was the TH-cam vids. I made a contact from SE Idaho to Japan on 18 meters. His window was open just long enough and the band faded. After years of owning it i could no longer remember which end of the unun was antenna or coax side and called. The guy on the phone was surprise to find out there was still a V1 out there still working and said very few were and that in the move they lost all the documentation and the original website data had been lost.
My only option is to take it apart and check it out. But i'm thinking of just tossing up 124.5 feet of wire and making a 9:1 unun and calling it a day. [edit] i sent to QRZ to get the link to the contact page and i found their members area seemed to be obliterated. Split up and sold off to 3rd party sites. And or took what they had and chopped it up calling parts of it standard and parts premium. Been a couple of years since i've been there.
Seems they have a free premium trial....

Nice honest review you really can’t go wrong with a loop.... But l can’t believe the price there asking.... l know it’s great build quality.... they could at least thrown in a decent vacuum capacitor
A brand new vaccum capacitor to cover 10M to 80M cost about $1,100 each if purchased in large quantity from Jennings.
@@carllavoie3804 okay l should do my reseach
Hi I have a Portable Loop CHA F-LOOP 3.0 I have not been able to lower the SWR and I have moved it throughout the apartment which is your advice
Contact Chameleon.
I’m not familiar with whisper, I’m looking for a ham radio antenna that does voice communication, does this do that? I’m thinking of getting the Xaigu x6100
New to ham radio, I was interested in Morse code. Would this work with a mountain topper transceiver? I'm not super clear on what antenna is needed.
I truly love it chameleon made a really nice duffel bag to put the antenna in that makes the antenna even better that you could load it in that bag and carry it off to the country or to the woods and set up really love it man chameleon is number one I'm definitely going to buy that antenna
👍👍👍👍👍
Thanks for a very thorough walk-through!
I am a total newbie.
Just ordered my very first SDR Bundle kit from RTL-SDR Blog.
May I ask:
1. Would this work with RTL-SDR Blog v3 to receive HF in Direct sampling Q mode?
2. Perhaps there is something else more suiting for indoor apartment use?
Once again, thanks.
How about if used tethered to a balloon up 1000ft would you loose to much by having that long of cable feed , Thank you
Nice video. Disappointed you didn't do the test with the 705. 😟
Definitely going to have a go at making a loop antenna. It seems expensive for what is mostly coax.
It wouldn’t be any different with the 705. I ran the test at 5 watts.
The capacitor is the expensive part.
Top notch video as usual. Have you ever gotten a chance to test out any of the Ciro Mazonni loops. I'm looking to either put a transmitting loop in my attic or outside on my chimney about 20ft off the ground. Any recommendations for me would be greatly appreciated.
Such a great explanation - much appreciated!
Great video! I'm looking into HF soon, and I've been eyeballing the Chameleon antennas. Would you please also consider reviewing the Chameleon MPAS antenna and comparing the two antennas? Thanks!
MPAS 2.0 is a great antenna, can handle 100 Watts and I've made several contacts from Ireland to South America on 20 Meters SSB @100 watts in the Summer 2020 in the Evenings and night UTC using just the single supplied counterpoise and the CAP HAT which I purchased separately. I do have a very low noise floor where I live too helping me hear lots of DX. It's also a fabulous SW receiving antenna, One thing that struck me is how quiet it is on receive compared to my wire antennas, I thought the Verticals were supposed to be noisier but the MPAS 2.0 is very quiet, again my area in the sticks is very quiet.
The first night I set it up and heard a Brazilian station repeat my call, well, you can just imagine my face!
I haven't used the wire antenna much but this would give much better performance on 160 and 80m but it still gets out well on FT8 on 80 and 160 on the vertical.
It works so well I decided to leave it up all the time and take it down only for portable use, the exact opposite of what I bought it for but at least I'm making good use of it.
I also have the excellent Super Antenna MP1, I even made a 1000 mile contact on 80m with the 80m Coil, but it can be a pain when band hopping going back and forth to adjust the coil, disconnecting the coax, hooking up to the analyser etc. The MPAS I can work several bands ( With the cap hat ) without a tuner.
Get the MPAS 2.0, it can handle 100 Watts and it just works, every time.
@@o00scorpion00o I really appreciate your insight. Your comments confirm most of what I've heard/read regarding the MPAS 2.0. I live in the burbs, so I have space limitations that drive me towards verticles over wire dipoles. I'm running an ICOM 7300, so I'm thinking the MPAS would be a good fit for my needs along with the radio's internal tuner. Portability and field comms matter to me as well, so I much prefer a rig that can be quickly set up and taken down. My primary focus in HF is phone/voice contacts, but might look into the digital modes more closely next year when time permits.
Good to know about the Super antenna. I looked at those as well and wasn't sure if all the adjusting/fiddling with it was worth it. Might take a second look. Thanks again!
I live in an area where security bars on houses are common. I have them on my house. Is that going to be a problem with this antenna type?
Guess it depends on how close to the bars you’re getting
That bag is about 5 times bigger than the original bag that the F Loop 2.0 came with. And that’s a good thing since thatLMR is so stiff it was a tight fit before to get all the stuff in the bag.
josh, another good video... can you tell me what small computer you are using there linked to the g90... thanks in advance...
It’s a GPD Pocket 2
It’s linked on my Amazon store in the description.
@@HamRadioCrashCourse Thanks Josh....appreciate it..
Did they send you this for free? I didn't hear you mention how you acquired this.
Thank you so much for doing a very nice edited video. (I hate live Premier shows and don't watch). I have the MFJ Magnetic Loop and to tell you the truth have not done much with it yet. Part of my problem is my XYL HOA. Castler stated is much be 20 feet off the ground. Therein lies the problem. To keep it out of sight I can only get it about five feet off the ground. Your video has spired me on to try again. Thanks for all you do.
Yep, you don’t need it up that high. Just one loops height above ground.
I think Dave's height recommendation for the MFJ-1786 was for it mounted horizontally where it has similar requirements to a dipole or wire antenna. For it mounted vertically, the tribal knowledge says one loop diameter and excessive height above a ground plane can be detrimental. 73 de WG2H
I see no signal difference between using my loop at ground level and my 2nd story shack.
Great Video! Thanks Josh, by the way with the help of your videos I got my basic w/honors here in Canada last weekend, your videos along with mike from K8MRD have really intrigued me and I'm quickly falling down the amateur radio hole haha. I look forward to the future live streams and maybe hearing from you on the air one day! 73 VE6JTW
Cheers!!!
Great demo. Can the power puck be used with the aluminum loop too? Also, am I reading it correctly that the aluminum loop is not good for 80m?
Yes and nope
Ive seen some reports that suggest the inner loop performs better if it connected off centre to the outer loop . Any comment?
Not sure. But I don’t quite understand what you’re asking.
@@HamRadioCrashCourse I was asking I suppose whether you have heard of that and agree that might work. Some propose making the inner loop more oval to increase the bandwidth of resonant frequency but moving it left or right?- not sure how that would work or what that would achieve unless it makes it more efficient for one band more than another?
I think **somebody** loves their IC-705. Just sayin’.
You’re right!
Josh, I love your practical videos, but this time I have to be rather critical:
There are very good reason that your viewers ask for SSB. I know it is convenient and easy to run Whisper and present a flashy chart - but it is meaningless without explantion: You told us that the SNR would reveal if the connection was actual useful for a SSB QSO - yet you only showed the map with the contacts - but not annotated with the SNR - so I am not a bit viser regarding range for SSB
Also, you briefly showd an effectiveness chart and then quickly closed it withhout explanation of the significance of the numbers. Does the 13% effectiveness with the Boost option mean I only get an effective 1.3W in the air when transmitting with 10W on 40m ?
I would love to see tests on SSB (!) with range and time of day included. Reason: I consider buying it - it is expensive - so I do not want to rely on sponsored videos only
Well said and valid criticism. Thanks for taking the time to write it out as you did. Let me do a follow-up. 👍
Hi,
can these bags also be bought without an antenna?
Thanks Ingo
Idk. Contact Chameleon.
Josh, if you lived in a condo and had a small balcony for one antenna what antenna would it be? Thx
Likely a loop. It’s more convenient.
Are you aware of any motors that you can use to turn these capacitor knobs universally fittable? If i have one in my loft I dont want to climb up to make every adjustment
Wouldn't it be nice and polite for him to reply to your valid question. That feature is key in the mag loop market.
Josh: Thank you for the video! I’ve been looking at this antenna for a solution to my portable HF needs. What is the tiny laptop you have? 73!
Interesting vid Josh. Thankyou! I gave it a ‘like’. Couple of comments:
1. Is your outdoor chair metal?
2. Some discussion re. Health and Safety aspects due to potentially high currents present at (especially) LF with magloops eg your XYL goes outside to hang the washing out while you are leaving it to do WSPR and she touches the non-rubber-booted PL259 assemblies to move it; minimum recommended distance between loop and operating position as a function of frequency (to avoid a permanent headache!)? etc.
3. Is there a (future) remote mechanical tuning option eg with a cable drive or motor drive for the case when you want it outside (eg your rv) while you are cosy inside so as to avoid constantly running in and out.
Thanks again,
Nick M1DDD
Nice review and info. I may have to get one of these. 73s K9DWB
Thanks...allways fun and informativ 2 se your videos... stay safe and have fun
Try 5 loops connect together,see how frequency comes up
do you see any problems using this with a icom 7100
It will work fine with the 7100 or any other radio for that matter. Just don't exceed the max power ratings. 25W SSB or 10W CW/Digital.
Hey Josh.
Tnx for another great video.
I didn’t have much luck with loops inside a hotel room. Have you ever tried it? Did it work with the CHA loop?
I really would appreciate your opinion about that.
73 de Rico, DG5BQ
You pretty much need a balcony.
@@HamRadioCrashCourse Well, some of the hotels do have one. But even if, they are quite narrow. I think the metal of the window or door frames behind the antenna would have negativ effects on the antenna. And I would only get have of it out while the other have would have to stay inside. So it’s just for the summertime 😉.
But many thanks for the quick reply.
Nice system, but QRP should be emphasized since the operator needs to be within arm's length of the antenna, which makes it easy to exceed radiation exposure limits. That's when a remote auto-tuner really is a value.
Thinking of this precise antenna in the UK a bit more expensive than US price though and no bag from what i see.
Hi Steve, I bought this antenna from Radioworld in the UK (early November) and you get the bag if you order the total version. Not sure about the standard though.
I'm still waiting for Chameleon Antenna to build a "matcher" much like the "CHA-MIL Hybrid rated @500 watts" to handle a kilowatt - so, those of us working from an apartment with a balcony railing can run a decent amplifier on the lower HF bands. I REALLY just want to be able to transmit a solid 500 watts everywhere I can, because it make me feel whole and complete, (sarcastically speaking, lol).
KD8EFQ/73
Good video.
Très intéressant et encore merci pour cette super vidéo.
Do they have a 100 watt version? A 1500 watt version?
Jeff N9NJN
Not yet but a 100W 10M to 40M is under testing/design.
Cool. Life is to short for QRP lol
What is the diameter of outer circle?
How does it do for local use, (NVIS)?
I have not tried it specifically for NVIS, but I have made every close in contacts with it on 40 meters.
@@HamRadioCrashCourse Would I need to do anything different to operate NVIS? How low to the ground do you recommend keeping the antenna for normal operation and for NVIS? Thanks! W2QLH 73
I've used mine, checking-in on an 80m net, with Net control being 45mi away, and several 20-30mi distance 10m contacts with ease, but band conditions will always play a part in my success (or lack of).
So how do you aim the thing?
Loops are directional off the ends, not broadside.
wow the weather looks way better there than in the UK :)
Ps your grass needs cutting :) :) Ha Ha
Every time I shoot in the backyard we’re in between mowings. Bad timing. Gardeners come twice a month. 🤣
Well I was watching your video and the one thing that I didn't see you show was the aluminum loop it I'm assuming it's just one solid loop that you can't collapse it and put it into the backpack that's what I was looking forward to seeing but you never did anything it just cut to the very end here and you see the aluminum loop so it I'm assuming that it's just one solid piece that you can't collapse and put it in the backpack.
Is that really LMR-400 coax?
Actually yes, the outer loops are lmr-400
Great video and I'm sure the antenna works very well but I feel it's too fiddly and to much tuning, everytime you move you have to retune , I live in the uk and this is not going to get used for 5 months of the year with winter weather high winds and rain I wouldn't want to keep running outside to tune even on a pleasant day , lot of money for what cannot be made a permanent fixture outside and to big to leave up in the house
I received my loop about a month ago (in the UK) and can confirm that it does indeed work well (indoors), I would go for it personally.
WSPR will only tell you how far/well your WSPR will go. It will not tell you a thing about SSB propaganda. Which is why I just go ahead and test on the mode I wish to use, mainly SSB. I do have and use my Chameleon F-Loop. It works like you said. I use it indoors in my bedroom for HF contacts. I also tried it in outdoors in New York City’s Central Park once and made some contacts. 73 de N2LRB.
I’m not sure why you say that. Of your report is 0 or higher, Ssb to that location is likely possible. Just need to look at the numbers.
How can i order here from Philippines
Contact Chameleon Antenna. I'm pretty sure they ship anywhere in the world.
Alpha antennas go to 100W!
Josh, I need your help! I live in a condo on the second floor. I have a balcony that is 4x8, closed off on three sides. I bought a Super Antenna and I couldn't get out. 😔 Now I'm going to by a magnetic loop antenna but which one should I get? The Cha F-Loop or The Alpha Loop Antenna??? I hear Cha Antennas are a solid build but Alpha's say's it 100W.... Which one would you pick between the two? Please help, thanks in advance & you are the best ham radio channel on TH-cam yes even better than that guy in Texas hahaha.

Build it, great fun to do and the cost is minimal.
So I suppose putting this up on your house roof is out of the question......unless you like climbing up and down the ladder?
Fine
All this stuff looks really fun. Must be nice to have a ham radio license. FCC is refusing to give me mine. I passed all three tests in April 2019. But FCC is keeping my FRN status "pending" because I checked the felony box. Yeah, I made a mistake in the past. I guess they're afraid I'm going to talk someone to death. At least I tried the legal route. I'm gonna start keying my ham radio down anyway with a fake call sign. Hey, I tried...
If there is a giant power grid shutdown nationwide, will this prevent us from using the hams completely?
No. We’re not dependent on the grid. Just solar charge it my dude.
Guess you left out the very high Q on small loops at low Freq and the extremely low Bandwidth and huge phase shifts for SSB type signals that then sound terrible.
He literally says they are high Q and and have an extremely narrow bandwidth (when looking at and based on a representation of a typical SWR curve). What on earth are you talking about?
my mazzoni midi loop can handle 800 watts
This is a great antenna for QRP. Chameleon only makes great antennas. It is too steep for my budget.
So how many got F-d watching this?
Not..and instead bought the antenna. 😂
How can they be a resonant antenna? They're quite the opposite really, especially when considering they're designed to operate on such a broad frequency range in just one or two lengths. I'm a CBer and I know that (101 basics), like the rapper of that song.
And you really shouldn't keep saying loop antennas, in reference to certain characteristics. The category of antennae is small loop. This is misleading for beginners when compared to an actual resonant loop.
