- Test #3 Experimenting with More, but Shorter Radials on the Wolf River Coils Antenna.
I'm using 15, 2.5 meter radials instead of the 3, 10 meter radials that come with the antenna. How will it work out? Watch and see for yourself.

Great follow-up video on shorter radials for the Wolf River Coil antenna.
That’s some great editing. It’s nice to see both sides of the QSO. KB9JQU was killing it.
73, de N4HNH
Thank you very much.
Another great activation for you Mike. Thanks again for the tip about shorten the radials. I was going to do some radio outside but that heat lately is a killer. 🤣 You definitely deserved that beer afterwards. 🤣
Great video, me and my friend made bundles of radials that size {after reviewing your video} in different AWG configurations. Ive used it at my house on top of large sheet metal sections {old historical metal that im using to keep bamboo from coming back} and creates a wonderful ground plane. Im looking fwd to my first park activation and will be sure to try this out. Just love your videos! Holler from Central Texas!
What is the math (or maybe the rule-of-thumb) behind your 15 radials @ 2.5 meters arrangement? I would have assumed 16 radials @ 2.5 meters would have been the goal so that it added up to 40 meters of wire? I generally aim for a combination of wire lengths to add up to 1 wavelength on the lowest band I plan to operate
I assume the change in math was to divide by 4 instead of 5, that way keeping it as 1/4 wavelength multiple?
So, Mike, of all the Wolf River Coils options that are available (coils, stands, whips, etc.) and also considering all the third party whips one can attach, do you have a favorite configuration right now? I'm looking for a good POTA option, but perhaps a good SOTA option too.
Glad to see you got the 2.5m radials up. I've been using them for a couple weeks now. Thanks for the idea!
Awesome job of editing our QSO Mike! That is very cool! Great to know that we can shorten those radials and make for more compact deployments. 73 de KB9JQU
Heck yeah, that was awesome to see both sides of the QSO. Thanks for sending it over.
Because ... that's why ... Love it!
SUGAR!!! Great video Mike. Glad to make the cut. Also, if I do say so myself, I sound GREAT! HAHA. 73 W7RGS SUHR
Thanks Mike for sharing your ideas, set up, and results. Going to give this a try myself!
Hi Mike. great video. I love experimenting with antennas and this is helpful for my 40-6m 17' whip with wire. I use a 17' whip on a mirror mount with a length of wire clipped on running to a fishing pole for an inverted L at 40m. 20m and up use the whip only. I have been using 4 33' radials, and 4 15' radials. Going to try using more short radials because the higher bands tune better when I roll up the longer radials. Good food for thought.
I have been trying to get my WAS with my G90 on ssb. I have two contacts with you in my log on QRZ, and they both show as TX, not MI. I have no confirmed MI contacts, and didn't realize you worked from TX. October last year, and April this year.
It's funny, I need HI, SD, MI, IA, and CT to get it from WI.

I found when I eventually got to 18 11ft radials I got a very low swr on all bands using the mini coil and 17ft whip. The 20 meter band low swr entire band and also the 40 meter band. I only needed to use the coil for the 40 meter band and I had low swr about 1:3:1 the entire band. The other bands swr the highest about 1:3:1.
18, 11ft radials worked good on 80m? You said all bands but did you try 80m? I use the 17ft Cha-Whip and the mini coil on 80 but can’t get the swr below 2.1 with 16, 16ft radials.
My Elmer would have told me to throw radials in the lake. Really helped at Winter Field Day.
I check myself for spots, I don't spot myself. Dam monkey pox.
You always get a pileup. Nice work. What logging app were you using? 😉
Have you seen KB9VBR you tube using aluminum screen 3' X 7' ROLL instead of the radials...any thoughts on it.

Just ordered a Wolf River Coils TIA for POTA. Cant wait to get it in the mail and try this with mine too!
Great video!
Mike - I am running 18x33' radials and get 1.03 SWR ON 15m and 1.04 on 20m, I have another bundle of 6x33' but I think I'm close enough. More metal on the ground , the better it seems
Hey mike...Mike.... I heard Paul from alaska..Alaska... I have picked him up a few times from Detroit. I run a wrc mini with 213 whip. I have tried 2 different radial setups. I was run I g8 31' radials
I’m still trying to find out if you prefer this version or the center loaded WRC setup.
OOO that sun got you pretty ban looks if you are loosing oils
I just watched one of your videos from a few years ago where you used an Ft891, MFJ 939 and the Tenntenna. Do you prefer a set up like this to something slightly smaller and more compact or is it more fun to really set up shop like this with a larger radio, battery and awning? I’m studying for my General and extremely excited to get in to POTA and SOTA. I love your videos man, huge inspiration. Thanks and 73 from KC1IAM.
You know that's a hard question to answer. I started off with the WRC but quickly developed a crippling addiction to antennas. It really depends on where I'm going and what the landscape is honestly. I recommend having a couple antennas in your kit. As far as the physical act of setting up, it's the same regardless of size equipment (other than the pop up canopy perhaps). Just more weight. If I'm going hiking, I'm certainly not going to bring the big stuff, but going from car to table isn't a big deal. The best advise I could give you is to evaluate the pros and cons of each type of setup and go with whatever one checks off the most boxes. There is no one solution for everything. Good luck on your General! I hope this answer helps and I hope to catch you on the air!
Where can I get the rails on your 7300? Mine is just a shack queen but they look slick. Also, glad I’m not the only one that says “yep” “uh-huh” “mm-hm” the radio while the other guy is talking like they’re in the room with me lol
There's a video for that th-cam.com/video/BP7zu2QXENU/w-d-xo.html
Great video Mike when you started I noticed it was starting piles enjoying is the pileup that you have that’s always fun. far you try to stay cool

Hey Mike. I used the wolf river coil 1000 silver bullet. With 2.5 radials. And the yeasu 891. Dude your awesome.. kk7 juj 73. For the tem meter band drop the antenna two extensions.
Am new about 3 months into HF but haven't done much ssb voice yet. But your videos are giving me confidence, Thank You 73 ,N6ZKI
This video got me wondering can you use a ribbon wire for radials? For instance if you used 3 ribbon wires made up of 4 wires each. Would you antenna see it like 12 radials or just 3?
Hmm, that's a good question. I'll expect a full report on your findings in the morning.
@@hamradiotube If I do it before you I will report back. This and the screen idea is interesting. Until then think of it as a content idea, no charge :)
Hey mike... I havea wrc mini with a 213 whip, and using a spike mount also ( mine is 3/4 stainless steel rod, In the ground about 12" - 18". I started off with using 8 31' radials. I made contact with you on that same setup from dodge #4. After watch8ng calls Sandra your video, I. Now running 15 10' radials, and haven't noticed much difference. The NL7V station from alaska, paul..Paul... I have made contact with him on both radials setus..setup... very similar rst reports. Just wanted to share another test situation. I do like the shorter radials, as it is faster setup and tear down. 73 KU8RLY
I wonder if the 15 2.5M radials will work will with a 112" folding antenna like the CHA MIL 2.0 (7 sections that are 17" long). Thoughts?
Would love to see if gauge of wire matters for radials. I see alot of 18awg radials, but there is alot of 26awg. That is a huge difference. for portable use with couple dozen radials, thinner would be better and cheaper BUT is 26awg as effective as 18awg. If not, by how much?? negligible? like 15watts vs 20 watts or is it like 15watts to 45 watts?
I’m picking up a WRC SB-1000 today from a local ham. I’m going to set it up like this. In mid May I’m going to be in Ouachitia and Ozark national forest, maybe I’ll be able to catch you on a POTA trip. I’ll be mostly running trails in the Jeep, but I plan on doing some POTA also.
Excellent results! Thanks for the experiment. I will be getting one of their antennas. I think I need a bit higher output than my QRP transceiver gives me though. 3 to 5 watts is hard to consistently make contacts with. Love your videos. N7MRF 73s.
What is your power setting? 73s W4IOS
Heck I don't remember. 90-100 watts I'd guess. That's usually what I use for SSB. Don't see this being any different.
I love my WRC antenna, too!
@hamradiotube what's the video you added the LDG RU-1:1 unun to the Wolf river coil antenna?
Nice experiment. I watched Callum's video on this and am now wanting to do this to my Wolf River TIA.
Thanks for the video.
What wire did you use for your shortened radials?
Brad
NØDPR
I have one. Haven't used it too much lately. TOO HOT. I'll have to try the 15 RAD.😁😁
Another great video. I appreciate your enthusiasm. 73's Ka4wht
Well you do know ground radials on the ground don't need to be exact because the ground detunes them............
Ayyyy I finally got into a video! Haha thanks for the QSO Mike. AA7KR.
I am thinking four 2.5 meter pieces of 4 conductor rotor flat lead might be cool.
..
I run 20-13ft under mine….. it’s my go to when portable.
How long does the 30ah battery last you, and how much power did you run that day?
Hi Mike, You could have done a dubble activation Parks and Lakes !!! nice, thanks
What type of wire are you using for the counterpoise wires and where did you get it from? And gage?
Amazing conditions, Alaska to Puerto Rico and Venezuela
Another great video, glad to have finally met you at the Baytown Hamfest.
Can't beat them can ya Mike... I use one when I can and find it great!
Mike I want to get a Wolf River (to go with my TN07). I was on their site. What do I order? I would like 10 to 80, 102" whip, and a sturdy stand. Their site I am sure makes sense to many (not me). Sorry to bug you. Thank you for the great videos. I really appreciate the help on everything you do.r
You would want their Take It Along (TIA) Silver Bullet 1000 with the Mega Tripod. It's on their order page. wolfrivercoils.com/order.html
Interesting stuff. It’s informative to read the experimental work of Rudi Severns, N6LF - he has well characterised the effect of radial length on antenna efficiency. Of particular interest is one paper in which he discusses the implication of radial length with respect to position of the current maximum along the radial, its effect on ground losses and therefore signal strength. That article caused me to review my understanding of length of radials on the ground. It’s probably more complex than we’re taught - the length probably does matter. I now carry a set of radials for each band - they’re not a random length and they’re not 1/4 wavelength either. Rudi’s work is well worth the read. Happy experimenting.
I reference him in earlier chapters of this series.
Hi Mike, I got right on this project and got my radials cut and installed. for 20M. My first two contacts were to SA and my third was to European Russia. SFI was 165, so that also helped. The smaller footprint of this antenna is going to be a big plus when setting up! Thanks for your hard work!
Also made a SSB contact to ZL land with the same setup.
Can you use 2 coils and get it to tune to 2mtrs on the ft891?
Good activation, 73 from EA5FUZ
Hi Mike , just ordered my WRC kit and I've been doing a lot of TH-cam "research". You have the radials in this video at 2.5Meters X 15 and that involves Callum's wizardry. This video is a year old have those wizard numbers updated or is 15X2.5M radials still good?
My understanding is the more wire down the better so if you have 100 feet of wire it should roughly perform equally regardless how many radials you have though I firmly believe for the lower bands like 80 and 40 3 33 footers would be better than 10 10 foot radials radials I wouldn't be surprised if 20 10 foot radials would out perform 3 33 foot radials on 80 and 40 just because it's twice as much wire on the ground I could be wrong though I am kinda dumb after all
Does it matter how long the coax is? I heard that it needs to be 50 Feet Long.
I've used 35' and 50' SWR was the same for me
Many short radials = Capacitive coupling to ground... and since you are right next to that lake, it should be a very good ground! :) -- I think that I am going to stay away from using computer or phone for logging... seems to be much easier to write it down! - but you seem to be doing great with that setup! :) -- You are making me feel like trying to get out to some park, and do some more activations!!! Thanks!! and hope you had lots of fun! :)
What size whip are you using mike??
I guess I'm cutting some wire this weekend!
Awesome! Need to get mine out there for a POTA!
How does this antenna compare to the TN-02?
Now you tell me. I just finished making up 15 2meter radials for my Wolf River.
Oh no!! I literally soldered another half meter to every one of my radials.
what a great Ham op
really awsome video sir
What happens if you just sit the antenna in the water?
Fantastic. Bloody brilliant!
You are the POTA daddy 2
I try
does wire diameter matter for the radials? Just got my WRC TIA mini yesterday
I would think that the bigger gauge could improve how well it gets out, since it would have more surface area to radiate from. I have also heard stranded works better than solid core, also because of surface area.
Whip 8'6" i think.
What size whip are you using? 73 DE KN4IQE
Any gators in your lake ? LOL
Not to digress, but how long are you getting with the 7300 on that battery?
I don't know. I've never ran it down.
Thumbs up if that intro guitar squeal made you jump and pissed you off a little. 😂
hey... this is not the antenna being good, it's the propagation being opened. For reference: with a vertical on ground level and 100 watts your average reach (from mid USA) is middle east, in 20 meters. Talking to Europe should be very easy.
Hey we got Mr. Buzz Killington here!!
@@hamradiotube 😂
Mike, great job on the activation. You were knocking them out. I know it was hot out there. The last week or so has been killer.
