The FARs (and I don't mean Farz as in distance) will not allow the use of a magmount on an aircraft.

He did say off road.

It's funny you mention this. Just today I was driving around metro Atlanta running some errands. I had my CB on 19 and my GMRS on Channel 20 with the tone set at 141.3. For a solid 5 minutes, I was getting RX transmissions but I couldn't hear anything. It would light up green, go dark, then light up again and repeat. Over and over. It makes me wonder what was happening? I reckon someone was transmitting on 20 but with different tones? If so, who or what and at 70 mph, I was covering a lot of ground in 5 minutes for simplex to still be working. I didn't have the ability in traffic at speed to take the tones off to see if I could hear them.

Interesting. What timing?

Yeah that looks way different. When I try to cut anything from this list is just does nothing and just reverts back to this stock look.This is the CPS from B2wr where I bought the unit. Of course anything past ch30 I can put anything I want with no issues. Perhaps the OG poster was using same software and creating issues. I think Chirp or RT systems might allow such edits.

A road has intersections, stop signs and stoplights.. A highway, aka a freeway, does not.

How do you distinguish road from highway?

At what frequency is that 4.6:1 SWR? Do you have an antenna analyzer that will sweep the range from 462 to 468 MHz so you can see where the minimum SWR ratio occurs? Maybe the antenna just needs tuning.

we use ch 5...

In Florida we use 16 as the off road simplex channel. 19 as the road channel. 20 as the highway channel with the tone of 141.3

I'm sorry: the thread went off the rails and i missed this information. It's, probably, too large. You can try sticking in rods that fit, they can even droop a bit, and try shorter lengths. Seriously: If you can cut a coat hanger and if it will fit, not strip threads and not droop much, the field will not know. It wont last but you can experiment.

Yeah, it’s like one of those vampires in a late night tv show. You put it down, then a short while later it gets back up again.

Now That Is Too Funny..... What "Valley Girls / Guys" Do On The West Coat, Has No Relevance On What GMRS Operators Do & Operate In The Midwest & Eastern Side Of The US. That's Why I Started My Response Post - "Here We Go."

All the cool-kids use GMRS Ch19..

Here We Go.... Before All The Weekend Powers To Be Chime In - Simple Answer Is NO. There Are No Currently Designated GMRS Frequencies Designated As Travel Channels. Use The GMRS Frequencies For However You Prefer On Your Travels.......

Nope

OK, Has any GMRS frequency been nailed down yet as THE Travel frequency?

Images of what I have, the Browning LMR-400 cables are a 25' run down the inside of the pole to a lightening arrestor in the ground attached to a 50' to the Radio. Currently, I have the Midland MXTA-26 antenna on it, trying to see if any difference in SWRs, maybe .1-.3 difference.

The aforementioned Tram above which is mounted on my flagpole 25' up

Not if you bought it on Amazon... True. I bought mine direct from Retevis. I thought I was doing Retevis a favor by cutting out the middleman. Proves again, no good deed goes unpunished.

My point is the two different lengths of the poles make for 3 differently tuned ground planes. I paid no attention to the frequencies the plane offered; it was not easily available. One length is one band, the other a second and combined you end up with the cheaper 20" 'UHF' option. The cheaper one will work but you have no ability to trim/tune it on the plane. That is assuming Nagoya has the assembly for each band somewhere. You can guess around 8" is GMRS if nowhere else to start and try the other one for best SWR. I doubt 20" is optimal for any GMRS antenna. There are reasons, I'm not getting into, why this is not as much an issue on a car but I will add moving the magnet around is enough to 'tune' the plane on a mostly-flat metallic surface >8". Edit- For some reason I referred to the other one as cheaper when it is $10.00 more. Does not change my 'opinion'.

Not if you bought it on Amazon...

No response from Retevis as of today. Despite being cooperative, polite, and giving them all the photos and information they requested over multiple emails (as detailed in my earlier posts), Retevis has not responded since my last post on this subject back in April. So I cannot recommend Retevis. They sold me a defective radio and do not stand behind their products, in my experience. If you get a dud, you've just thrown your money away. Buyer beware. Radioddity, on the other hand, did take care of me, and I CAN recommend them.

I literally clicked on both link and looked at them. That's how I knew what they looked like. You asked, acontextually, which one was best. You gave no context. And then you started insulting the people and software they are running who are trying to help you.

To what do you have the antenna mounted?
