#Hamradio #kc5hwb #mnhr - แนวปฏิบัติและการใช้ชีวิต
I've said it before and I'll say it again - I think you have the highest real content-to-BS ratio of any HR TH-camr out there Jason. Very valuable. Thank You !
Thanks
I picked up this antenna and am using it with my FT-891, because it can handle 100W SSB. It performs surprisingly well for me, and tuning it to get to SWR around 1.2 or lower is very easy with a counterpoise cut for each band (180/frequency=length in feet). I know I've heard of people using metal tape measures so they don't have to have separate counterpoise wires per band as well. Once you know roughly how many segments of the whip to extend for each band with that antenna it's very easy to make small adjustments to the whip to dial in the SWR and get on the air. I actually picked this up for SOTA use for summits where there are no trees and not an easy way to get a mast up, and it has worked surprisingly well for that.
Yes agree completely. Also I find that the counterpoise has to be at least 2.5’ off the ground for acceptable SWR. Just throwing the CP on the ground doesn’t work.
So at that point, with a raised CP getting in the way, you may as well use an efhw on a fishing pole.
I've bought from KM4MPF sales here in Tennessee at some ham fests. He has a good selection to choose from. Anything from antennas to connectors, coax and just about everything in between.
Did the same with my comet 350...scored the end with rings for 20m and 40m.
That was funny to watch. I've got the same antenna and have tried using it just as you did with the 705. I'm still trying to make a contact lol.
I have heard that a counterpoise is very important to the efficient operation of the Comet HFJ 350M vertical. I am planning on connecting this antenna to the 20 radials of my DX Commander Expedition to see how it plays...
Perhaps, but it isn't 100% necessary because I just made contacts with a low SWR and no radials.
@@HamRadio2 Ah, but would your 52 have become a 59 with a counterpoise? :) I've seen a number of videos saying it's "necessary" -- and sure, you prove it technically isn't... and yet.... physics, right? Such things could help??
I have good fun with an MFJ-1820T on 20m, it only works with a counterpoise but for such an antenna it's surprised me.
I also have fun with the DL1DN whip, you have to touch the ground on the antenna, you become the counterpoise but it works well.
Other antennas I like portable are the MFJ-9232 QRP loop tuner, no counterpoise needed and it works well, probably better than loaded short whip. I've made decent contacts from Ireland to Russia with it and beyond with 5 watts and just 2 meter circumference antenna of 10mm soft copper pipe. You make different loops sizes for different bands but it works well.
It has a screw on the side of it Jason you can run a counterpoise just around run quarter wave counterpoises for each band and you'll get a flat s WR super flat just adjust the top of the antenna just a little bit up and down and you'll achieve a flat as WR with it but you got to run a counter please
The toy box antennas rugged it looks great yeah man congratulations on your contact I like that antenna thanks for sharing it 👍
I have this antenna and from my QTH in Georgia, I've reached Minnesota, Canada, Memphis and Florida with this antenna. My only problem is that I can't get consistent results so I'm going to play with the counterpoise more and see if I can get that consistency I need to make this a reliable part of my kit
I think I will try a counter-poise next time also
@@HamRadio2 I will say this. It's an excellent Listening Antenna.
If you added the long counter poise wire unto the counterpoise lug on the bottom of the antenna you would have been heard by all those signals coming in.
I experimented with this antenna and was careful to measure my counterpoise leads and it is total crap. Couldn't get an acceptable SWR anywhere on the HF bands. Even used my antenna analyzer to help find the antenna's sweet spot. There wasn't one! Had the same setup as you: IC-705, Windcamp mount, HFJ-350M.
Thanks for sharing this video - you covered all the points I wanted to know about. 73 ES GD DX
pretty much a similar experience I had with my 350M. Ended up getting an EFHW instead
It's best to have both! :)
I like the setup and hope to be out on QRP again with this radio! De WV1Q 73
When your next door trailer with metal siding is higher than your antenna, what could possibly go wrong? lol I wonder what would happen if you connected a coax and mounted the antenna on top of the trailer?
I have not been able to make a single contact using this antenna on any band when used with an FT-817ND. It does listen well though.
Nice video thanks for sharing Might try it with my Xiegu G90.
You should!
It definitely works better with the G-90. I have both the 705 and the G-90
@@walteredwards544 Walter - how's it working with your g90 and are you making contacts? I just picked up a g90 and looking for a portable antenna.
@@walteredwards544 how does the radio make a difference? I’ve heard of a lot of factors affecting antennas but not the radio.
@@truckinguy92 It just seems that the extra power pushes out more signal farther 20 watt's vs 10 watts
You all should put the list in the description. Possibly somewhere at the top.
Not a bad idea - most of the time, MY video is posted long before the list is created, though.
7 months ago you said you wouldn't buy it...5 months later you are making videos on it....boy you are a fan.
I would like you to point out the time where I said I wouldn't buy it. Please find that and link it here. I will wait....
@@HamRadio2 well it's more of why you should not buy ...th-cam.com/video/NsDHdE3X3Uw/w-d-xo.html and which would also mean why would you then want to buy? But either way appreciate the response...keep up the good work.
Other folks have come along and said the same thing, and they were clearly trolling me because it was obvious they didn't watch the video. If that isn't you, then I apologize because that is what I thought you were saying.
In that video, I clearly state that I WAS, in fact, planning to purchase that radio, and that I recommended someone not purchase it if they didn't understand what QRP was. I have several QRP radios and enjoy that type of operation.
@@HamRadio2 all good no need to apologize. I like watching your videos a wealth of knowledge. Very close to buying one myself. Like so close I literally nearly pressed the buy now button 5ish or so mins ago....but quickly logic cut in. What's needed right now new car to get to and fro work or radio? Hence held back.
@@foodconnoisseur8397 Thanks for being here.
You have to use a counterpoise with this antenna or you will not get it to work. It works ok with a counterpoise
I wasn't using a counter-poise in this video and I made contacts and SWR was good, so no...you don't *have* to use one, but I suspect you will get easier results by using one.
Thanks for the video, I will have this set up very soon, was there a final verdict on the counterpoise question? and I’m more interested in 20/40 meters, like an average length for tuning? Thanks again for any suggestions
I used this antenna at the weekend and made a contact with 10W from my RF 'noisy' QTH location - I was able to tune the SWR on 40, 20 and 17m easily with a rigexpert. Would i recommend this antenna - absolutely !!! I'm looking forward to getting out from an urban environment to try it out.
Didn't mentioned the counterpoise de VU3LYD
Correct. There was no mention of a counter-poise in the instructions either, nor did the antenna come with one.
Very cool. I’m jealous!
Thanks for watching!
What battery are you using ? And would the antenna be good for a xiegu g90 as well as the bracket?
This is the battery I was using in this video - amzn.to/390c8vu
finally what is your appreciation about this antenna. The good and the bad? do you recommend it? Thanks
Very nice antenna rated100watts
Are you running a counterpoise?
Nope
@@HamRadio2 I wonder if that would help.
@@RichardDePas Could be, but the instructions don't call for it so I wanted to use it like this first. I'll probably do something else with it later
@@HamRadio2 would love to see a follow up video with the results. I just picked up a 705 and planning some motorcycle mobile. That looks like a nice small antenna.
@@HamRadio2 my instructions said use a counterpoise and even told me the length per band if I remember correctly.
Did you have any counterpoise out with that contact???
No
Was you using the counterpoise? TIA
No
Mmm have you tried to attach a radial??
The Icom IC-705 has no antenna tuner.......... how was your SWR?
Any older stuff you wanna part with in radios , I have a Toyota Tacoma 2015 Tacoma looking for something decent to put in there
Do you have a video on tuning it?
Great video. You recommended this antenna to FT-3DR. Thanks
This is an HF antenna, not a VHF/UHF so it will not work on FT-3
@@dennisschultz1175 Thanks. Wich you recommend to use?
@@enrique861 I use a Signal Stick

Great review man.
How do you keep the windcamp bracket from loosening up and not supporting the antenna
Playlist: th-cam.com/play/PL01YuCls6edYrLBNgEJVrRmQge_9ErnbH.html
A Premium Coil Spring Metal (kids toy spring spiral) works probably as good and cost 5 bucks
Cut to the right length, you're probably right.
@@HamRadio2 Matchbox?
@@HamRadio2 p.s why not make a video, Toy Spring vs Comet antenna?
This antenna is a poor performer for low power QRP use..it starts working fairly well, for what it is, at 20 watts output power though
Great Video!!!! I could not help noticing that you mentioned you were tuned for 20M but at 8.54 you are tapped at 15 meters? Was that just an edit thing or was the special event on 15 meters?
I am sort of observant about that sort of thing because I have a loaded portable vert, and have operated on frequencies that my antenna wasn't tapped for...its usually the last thing I notice as I am taking down after a frustrating day of getting zero answers to my calls...LOL
Anyway, great video..keep them coming

That was just a photo I used as an overlay. The SWR while I was operating was near perfect
Have what might be a crazy question. Thinking of getting the HFJ-350M to take camping. (Its budget friendly and easily replaceable vs $300+ alternatives). Running counterpoise wire in a camp site can pose a trip/run into hazard, especially for kids. So here's my question: Is there any harm if I was to take high-vis (something like WEREWOLVES Reflective 550 Paracord) /glow-in-the dark 550 cord, and replacing the internal cords with stranded 26awg? I'm pretty sure the outer nylon sheath shouldn't affect the operation of the counterpoise/antenna but I'm not 100%. Anyone have any thoughts/suggestions? (Even if its: just "bad idea" or "good idea but use # AWG wire instead). Great videos, thanks in advance, and for posting the licensing classes (especially extra). I'm re-watching them in prep for upgrade testing.
I am a Marine Captain call sign WYD5692, i have an frn too. Can I transition to a tech? Also why are our call signs similar but different than yours.
Different radio service. I was AAT7XF while in Army MARS
@@JARyding would I still use my frn to apply?
Yes same FRN, but you would need to take a test and pass it to get a Ham Radio callsign
Where are you in Texas? Call is N5NNA Denton County Texas.

@@HamRadio2 Hickory Creek, owner of a new IC 705
If "Roger?", means, "Did you hear what I sent?", and, "Roger", means, "i received everything you sent.", then evidently ham clubs are helping people to get licenses, but not following through. They are turning them loose with no guidance, to "qsl? qsl? qsl? qsl," and then everyone is doing it, and "qsl," does not mean, "I received everything you sent." We are supposed to be competent radio operators. Sorry. I did enjoy the video on this antenna, and did not know that it even existed. i have an old Miracle Antenna, but don't have a QRP radio anymore. Looking at the IC-705 a lot these days, and know that it's very expensive, and may not get out that well, but trying to justify it for SWLing (anywhere I may be), and 10m(Anybody local on? Or someone might hear me if sporadic-E shows up-- on a base antenna), 6m(CW? and SSB and FM-- on a base antenna), 2m (Repeater and SSB-- mountaintop or base antenna, or in my car), and 440(430 SSB and repeater-- mountaintop or base antenna, car). I keep having a premonition of having a $1300 radio slip out of my hand and bouncing off of something bad (concrete or blacktop). I have a feeling that prices aren't coming down anytime soon, on new stuff, and that used radio gear prices are going to skyrocket. So perhaps an IC-705 is in my future. Maybe can attach a lanyard to it. 73 everybody.
With a proper counterpoise you dont need a tuner.
Oh no. That antenna is pure punishment.
I have the comet and I'm not that impressed. I feel like my comet is going to go on QRZ...
If I didn't just buy one I'd buy it.
These miniature antennas are ridiculous. Fine for listening, but don't expect them to perform miracles on transmit.
it is definitely a compromised antenna

I’ve been watching your Chanel. Good stuff. Actually I’ve watched all the training videos you have on license for ham operation. In these days it would be very important to have a way to communicate. I’m looking at hand held right now for my first radio just in case you would have to go mobile. I’ve been looking at the Japanese radios. Would you recommend tri band for a first radio? I want something I can get weather , police scans or emergency plus have the capability of contacting other operators. I’m looking at spending around 2 to $400. Any suggestions?
