Building a GMRS J Pole out of 14 gauge house wire.

Quick, easy, cheap J Pole build for the GMRS 462.550-467.725 band

[@Gruuvin1]

I built this antenna and tuned it to 1.05:1 SWR @ 463 MHz, using a NanoVNA. It was cheap and dead simple. I put it up 25 feet on a hill in the woods in North Georgia connected to a BTECH 50x2. I set the frequency to 462.725 MHz, set my phone next to the radio and started audio recording. I drove all over and into two towns; about a 10 mile radius in multiple directions, test transmitting everywhere from a 5W HT. This antenna picked up EVERY transmission! 10 miles simplex with 5W is NOT BAD AT ALL!

[@MrThisIsMeToo]

Congrats and glad to hear on such a successful build.

[@jordanmkurtz]

The wobbly end of the tape is to accommodate for whether you’re pushing or pulling on the hook. The wobbliness is exactly the thickness of the hook so it’s always accurate. Thanks for the video!

Beautifully and clearly presented step-by-step antenna project. Thanks for taking the time to put this together! [EDIT: A couple of hours after watching your video I raided my junkbox and built the GMRS J-Pole to your specs. It took me twice as long as you but it came out great with my CAA-500 Mark II showing 1.1:1 resonance at 464.5 MHz and 1.4:1 at the 467.7250 and 462.5625 GMRS band edges. I'll hang it off the side of the tower tomorrow weather permitting. Thanks again!]

A tip I learned is before you start, clamp one end of your wire in a vise, then use your drill to twist it. This straightens the wire and makes it quite rigid.

Good tip brother, just did this, my wire is as straight as an arrow now

[@Gruuvin1]

What a valuable video! Thank You! That was a good stopping point. For a base antenna that probably won't have too much difficulty hitting a local repeater, which receives on 467.625Mhz center frequency, but simplex 462.625Mhz between small 5W radios might be where you'll NEED your best performance.

[@lomgshorts3]

I commend this video because it will help anybody build an antenna for whatever service they are into. If you have the parts to build an antenna already, all you would have to source is the wire. I suggest using #10 AWG to lower the antenna "Q" and make it more broadbanded than it would be with #14 AWG. the project might take two hours to complete, including the time to mount it wherever you choose. I would mount it on a metal roof, or on a metal pole above the adjacent tree line for unobstructed access to a repeater. Good luck!

[@flyingskwerl-Outdoor_Adventure]

How about using 12g wire?

[@lomgshorts3]

Nice J pole for any frequency ! Just use the formula for a j pole and then trim for resonance. I would seal the PVC and use it as a radome to keep moisture out so it would not change the resonance any. Better to build an antenna and learn from it, than just buy it off the shelf and learn nothing. Well Done ! 73 de W4FJF.

If your antenna has a vswr of 1.2 after the first build just leave it like that. Is is excellent. It amounts to a reflection of only 0.8 %. Even 10 meter coax or a connector will cost you more power.

[@whiskyguzzler982]

No shame intended, since it was only this year that I learned why “the end of these things is always sloppy”. The tape measure is designed to move the end out when measuring outside diameter and in when measuring inside diameter. This accommodates the thickness of the tab on the end of the tape. This is a feature, not a defect.

Add 3/4 ground radials 1/4wave length long on base part of J Pole straight horizontal. mount antenna on a insulated pole ,so antenna floats. Ull find it will perform a lot better line of sight and better performance. I built one for PMR446 band ,works well.👍

[@dennisjones8991]

Use 1/4 or 3/16 inch copper tube, it will stand up better and all you have to do is spray a sealant on it to prevent corrosion, just like you would with 14 Ga wire, except, you do not need a supporting structure. Also, using the pipe will make the antenna more broad-banded for repeater use.

[@Gruuvin1]

Copper pipe isn't as easy to snip or solder. You only need 5Mhz of bandwidth. 1.5:1 for repeater inputs and 1.1:1 for simplex is tough to beat... not sure it's worth the added difficulty trying to build and tune pipe.

[@mor4y]

​@Gruuvin1 I mucked around with 8 and 10mm microbore copper heating pipe, originally just to connect to patch antennas I'd made, but after a bit of experimentation I was building yagis out of it and a few other things, and it's great stuff. I found various ways of cutting it, but the little screw down cutters that plumbing shops give away for free or next to nothing are the best 👌 the blade leaves a beveled edge, which seems to be more forgiving than the sharp edges that another cutter got me, and a hacksaw was useless, nearly always bend the length doing that And I use a spray ignition sealant for old ass cars that's actually a thin layer of wax unlike wd40 or others, that helps on anything really, stops condensation on pipes indoors too! 😂

[@kennethragland8117]

i have a couple questions 1- if you used sch-40 pipe would it hurt your rx and would if effect tuneing ? 2- ccan you use a larger wire say 10awg insulated or bare what would that effect ? Ok that's three questions sorry thank you wrug770

Going from 14 gauge to 12 gauge won't change much, but using bare wire will change the velocity factor and the listed dimensions will be too short.

Using a repeater puts you at 468. So if you hit repeaters might want to tune up higher. Remember the offset is plus 5 MHz.

[@ricksshop]

I agree SWR should be lowest where you transmit, but I spend most of my time on simplex. Final tuning should always be done with the antenna mounted in it's final location...

Most GMRS repeater receive at the lower end in 462. And Tx at the +5 in the 467. range making 468 the top end.

[@Gruuvin1]

If hitting your local repeater is not too difficult, you still may want to tune for best resonance at 462.6, because simplex to 5W handhelds is a lot more difficult than duplex to 50W repeaters.

Hello sir, thanks for the video. I’m new to GMRS radio so I ask forgiveness ahead of time for my question 😅 I noticed you soldered the center wire of the coax to one part of the house wire and then soldered the shielding to another part of the same wire. Why doesn’t that cause a problem? Seems like it would be bad to have antenna directly connected to ground. Or were they separated electrically and I missed it?

Hello Rick Thanks for the video and clear instructions. I meticulously followed your instructions and when it became time to test on my nanovna I got some real crazy results. I took the antenna out of the 200 psi PVC tube and I got reasonable test results. As soon as I slip the tube on, even just a couple of inches my test results flip out and shot up over 5 to 1. Take the tube off and then I slide down to 1.20 : 1.00. I double checked all measurements including the 5/8ths soldering points and everything is on the dot. Can you make a suggestion? Thx Tim KI7JBF

Expand the frequency range of the vna. What is probably happening is the PVC is changing the velocity factor of the antenna and pushing resonance lower...

Any conductive material will work, even stainless (whips have been made of stainless for years). Uninsulated wire will require less velocity factor, therefore will need to be slightly longer. Any material other than copper won't have the advantage of solder connections.

Hey guys its a simple end fed half wave antenna , that 1/4 wave lower section is only for matching the feeling impedance it's pretty much set at your coax impedance 50 ohms in this case , that's all this end is for. Now the portion above the j section is your radiating antenna it's the part that you trim for resonance if the frequency is to hi you need to add to it if the frequency to low trim off an 1/8th of an inch . now after you get an acceptable swr

[@geirha75]

The bend or the distance between elements? Isn't it critical? How much can we deviate? Any experience on that guys?

[@ricksshop]

I did some experimentation with wider and narrower separation, narrower seemed easier to tune. Part of it is the unshielded center conductor and ground become radiators, and that becomes more of an issue with UHF.

[@geirha75]

@@ricksshop Thanks for your answer. I was thinking of using the J-pole antenna with a scanner, one frequency only. Maybe it's less critical then. Given that I have bought copper pipes and t-joints it's kind of hard to design it with so tight separation at 469 MHz . It seems easier with a house wire.

Sorry cat sent last message before I was finished. After you get an acceptable swr reading You can assemble it in the tube but it's not going to be trailer omni due to several factors although is should be satisfactory , you need a choke on that coax to keep it from radiating although most people don't .now after you get it all ready to use try turning that antenna wile watching your field strength meter or s mater and you will notice its not omni so just turn it to get strongest signal on station you need and lock it down .

I might in the near future. 2 meter J antennas end up about 6 feet long, and the radiation pattern isn't optimal on 70 cm. Ed Fong builds an admirable 2 meter/70 cm dual bander that I won't copy, because he sells them for a good cause and encroaching there violates my ethics.

I'm new to J-pole and you made this look so easy! I had some 14-ga Romex left over so I grabbed that (and cut and bent to your dimensions). After sliding into 3' PVC up to the end, my NANOVNA showed resident freq at 471mHz. SWR was around 1.3:1. I was like, Ok, let me trim the ground a bit and the SWR went down, but the freq went higher. I thought maybe the 1/2" Wave portion was too short, so I built another longer version. I get the same 471mHz, but the SWR was around 2:1 .. what am I doing wrong? I wanted to center my freq around 465 (due to more repeater usage but still wanted to use Simplex.).

[@ricksshop]

Sounds like it was close with the first iteration. Full disclosure, the J pole in the video was my fourth attempt. The lengths at UHF frequencies are super critical. Try adding 1/8" to the short leg and 1/4" to the long leg and retest. Velocity factors for insulation and PVC vary, which might account for the discrepancy.

[@ricksshop]

@@SirRonmit It can, moving the match point up and down can change both SWR and center frequency.

[@NimblyJimbly]

The other thing that could be affecting your SWR is the type of PVC pipe you are using. Ideally, you should be using 200psi thin wall PVC. They sell it at HD, Lowes, Ace, etc. Also, apparently certain kinds of paint on the PVC can mess with SWR as well. I painted the pipe on one of my tri-band j poles with Rustoleum rattle can paint to camouflage it a bit and it killed the SWR of the antenna. Had to buy all new PVC. Ended up just leaving it bare. I've heard Krylon brand doesn't mess with SWR, but haven't tested.

[@johnyoung1128]

@@SirRonmitTheoretically changing the tapping point only changes the feed point impedance which does affect SWR. my approach would be to adjust the lengths to adjust resonant frequency as per the video and make a final adjustment by shifting the feed point a little. The low SWR figures that were shown in the video indicates that the position at 5/8 inch is fairly accurate.

[@victorb22622]

All your effort was prity good, but at the end,you missed to measure the final or tunes length of J which you dud cut

[@ricksshop]

I assure you, it was most deliberate. Changes in velocity factor, wire type, pipe used, installation location would all change the length of the final antenna, which is already difficult because of the UHF frequency (1/4 wavelength is only about 6").

[@jordanmkurtz]

Thoughts on using 18Ga wire? Too thin?
