Best GMRS Base Antenna? - Ed Fong GMRS J-pole Antenna

I got one in April and I use a 5 Watt Radio on it and I can get out 12 miles on it

[@ca8746]

I personally love the GMRS videos. I think the way to get more people involved in HAM radio is by promoting GMRS to get their foot in the door.

I disagree.. I'm my case.. Was getting a Icom 706 for ssb and 27,555 Then wanting to get to those other bands..lol

[@pupdaddymail]

I have Ed Fong's 2 band commercial antenna. It's a fantastic antenna and covers GMRS beautifully. I'm a big fan of his antennas.

[@robsummerhill7383]

I've been using Ed Fongs duel band antenna for 2 meter and 70CM for the last two years. It is fantastic!. In the PVC pipe it has withstood our 70 MPH Spring wind gust. Remember do not PVC Glue the end caps on! PVC pipe does dry out and become brittle after a few years in the sun. The end caps are much thicker and can be reused when the pipe body needs to be replaced. The end caps have never become loose while in use. I do use the duel band antenna for GMRS and it works just fine to hit a repeater 18 miles away.

[@imarat21]

The pvc adds a bit of capacitance which makes the antenna behave as it’s a bit longer. The thicker pvc would move the resonance down a bit.. Also a different diameter would also have an effect also..

[@brianmorton9430]

Just purchased the gmrs j-pole. Thanks! MXT400 is supposed to be landing around 17OCT. Just been gifted 40 tower. Will be working towards HAM before the end of the year. Good times. Good times.

[@charleszimmermann7784]

Love your channel, I really like that you cover a large variety of two way communications. I never understand hams that restrict themselves to just ham frequencies and visa versa. I have my ham license , GMRS license , I also utilize a citizens band radio. Thank you.

[@HamRadio2]

Thanks

[@taz9075]

Thank you and very interesting. I am all new to this and this maybe a stupid question but does it mount horizontally or vertically? Also how do you mount it? I might be getting ahead of everything and you will show it in a later video.

[@christophermcclellan8730]

Took me a while to figure this antenna out. A regular J Pole is 3/4λ in total length. 1/4+1/2. For GMRS that’s only about 17” and this one is much longer. The coil gives it away. It’s a collinear J Pole, so there’s a 1/5λ coil and then another 1/2λ radiator on the end, so it’s a little more than twice the length you’d expect, which is still only about as long as a dual band and should be around 5dBi instead of 3dBi.

[@mikemu0919]

Can you point me to the video where you tested Dr Fong's GMRS antenna? I've been very happy with his DBJ-1.

[@allafon4813]

[@justinvoytal8490]

Is the wire just free floating inside the tube? Could you paint the pvc or would that cause issues? And do you seal the pvc with pvc cement or is it just friction tight?

[@benjosevilla]

paint with non-metallic paint. Do not glue, just hand tighten. Yes the wire will just free float.

[@Frankh77]

Get something with some gain, like a Comet GP-9NC. Is the lower end of decent antennas, but great performance.

[@ronwolenski-n8wcr]

PVC is a dielectric, so thickness will affect RF...

[@kjb_tennessee]

Great video, would there be any problem using camo ultra flat paint on the pvc?

[@BigBadJones]

What is the best option, Gmrs or the Murs/gmrs dual band?

[@HamRadio2]

The GMRS antenna has more gain than the dual band model but if you need to use MURS also, then the dual band is the better option.

[@kb3icu]

[@martylwylie]

Please forgive me if this is a stupid question I'm new at this.. So well a tri band antenna work for GMRS or is it better to have a GMRS antenna? Thanks!

[@MrBOB39]

Not a Stupid question. Depends.. Bottom line..likely yes However..Tri-Band is for 2 meters 1.25 meter ( 220 mhz) and 70cm Murs is 151 to 154 mhz.. but 2 meters is at highest 148 mhz FRS/GMRS is 470 mhz But 70cm is 420 to 450 mhz Most will be happy getting and using the Tri-bander On Both MURS and FRS/GMRS Not all though ( like me )

[@karls4346]

What are your thoughts about mounting this to a vehicle for a mobile setup? Either mount it horizontal on the roof for a low profile or mount it on the trunk vertically. Love to hear some thoughts on this.

[@HamRadio2]

Not a good idea. You don't want to mount it horizontally because UHF FM is better with a vertical polarization antenna. Mounting it vertically on a car would destroy it - it isn't made for that type of wind resistance. There are other GMRS antennas made for mobile mount that will work much better.

[@karls4346]

@@HamRadio2 Much appreciated for the reply! My goal for the mobile was to get better SWR then the Midland Ghost Antenna can offer. So my thoughts were to mount a longer antenna horizontal to the roof. I suppose its not similar to surface area but height is the king. Do you have any better suggestions other then the Midland Ghost for a low profile GMRS antenna?

[@HamRadio2]

Some good choices here www.buytwowayradios.com/catalogsearch/result/?q=gmrs+antenna&cmid=amsreGRvTmttM0k9&afid=dVVPbGl2K2tzVDA9&ats=bHdLSkJuKyttWFU9

[@markallan4849]

Once you get that antenna hooked up it would be nice to get an SWR reading on it. And will different lengths of RG cable affect the SWR reading on that antenna?

[@wateroperator1972]

SWR is determined by the length of the antenna itself. Increasing the cable length will decrease power output depending upon the length and type of cable.

[@rudyxeijas5342]

Hi I have a question: can I know when you will have the GMRS version available?

[@HamRadio2]

A new shipment is en-route and will probably be here today or tomorrow

[@Quentyn73]

If signal resonates inside the tube, wouldn't that decrease the signal strength and quality?

[@buck2552jr100]

Unless I missed it, how do you properly ground this antenna? And would be suitable as a repeater antenna?

[@HamRadio2]

J-pole antennas do not need grounding, that is one of their features. You can use it for a repeater, sure - but you can probably find better antennas for repeater use.

It's in the description of the video. Here it is again grapevineamateurradio.com/collections/radio-gear/products/ed-fong-j-pole-antennas-dual-band-220-and-roll-up

[@paaao]

I made a mono band folded dipole for UHF, ham bands. They have a very wide bandwidth. I use it on GMRS and still don't pop up above about a 1.4 SWR at the high end.. All you need is some electrical PVC, and 1/4" stainless aluminum tubing. It's great for simplex. Gets out further than those j-poles or quarter (5/8) waves. Just need to build a 4:1 balun, and get a good 12" or so loop that's about 3 to 4" wide. Run it with your family horizontal and with a PL tone on both in/out. You'll kill it on GMRS simplex. If you want the exact dimensions, reply here and I'll get em to you. You also need good 1/2" hardline, or LMR-400 minimum to get real nice RX on GMRS. Most people use a vertical unbalanced antenna designed for horizon or repeaters, and they combine it with some cheap off the shelf coax. They stuff just doesn't work all that well

[@TrullaCæmentarìí]

Interested!

[@paaao]

My reply with details and links to build it got removed, so I dunno... scratch that I guess.

[@timin770]

I have this same GMRS antenna mounted just above my roof line on a PVC pipe. The clamps are plastic so there is no metal anywhere hear the antenna. The coax is about 50' LMR-400. The radio is a Wouxun KG-1000G. I am getting 1.8:1 VSWR on channel 22. I only have a Surecom SWR meter so take the reading with a grain of salt. I wonder if there's anything I can try to get the SWR down or if I should worry at all. Ed Fong's products and reputation are impeccable so I'm sure the problem is on my end

[@Chrisman23]

How long of cable can you run from antenna to base station before you start running into problems?

[@billkc3raa647]

Was all set to order one, but sold out. I am struggling with this GMRS stuff. I built a copper J-Pole and SWR is perfect. Anywhere from 1.01 to 1.4, but did I just build a dummy load? I thought I could hit some local repeaters, but this home brew antenna doesn't seem to receive very well all. Maybe my coax? I have no idea. The HT with rubber duckie picks up stuff the roof mounted J-Pole doesn't. As soon as he gets them in stock, I'll give it a shot. Nice review Jason

[@centralfloridagmrs]

The J-Pole gives me excellent Simplex coverage but I had a tough time getting my repeaters. I don't blame the J-Pole however.

It is tuned for GMRS, works Great, and holds up to wind and weather here in S.Texas . The only thing I would drop this antenna for would be if Comet made a gmrs version on the gp-9 in single band. Of course if they did they would probably stop making the CA-712EFC .

Hi Jason, I appreciate all the video content! Always good to hear what others have to say, their experiences in radio etc. In my experience, J-pole antennas have a major dead spot and are inherently hyper directional.
