The only way to know for sure is to put a meter or portable antenna analyzer on it and test it.. But, like the @mb523 said, its not going to work very well.
-
They are probably using more than one channel. Jump one on 600 jump 2 on 625 and no loop. They state you name your frequency and they program it. You don't have the option to change it.

Maybe one of these might get through your browser protection. https://www.google.com/search?client=firefox-b-1-e&q=retevis+daisy+chain+rt97l

That page does not come up for me.. But lets also take a moment to remember that Retevis also posted on their website and on Youtube, a video showing/proving that you can add their 25W external linear amplifier to the original RT97 and it will then output 25 watts.. They even showed a power-test on the video to prove it.. ..... Until a big GMRS youtuber came along and called them out by pointing out that it would output more power but it will not be able to RECEIVE anything because the amp is placed after the duplexer....and if you placed the amp before the internal duplexer that was rated for 5W, it would destroy it... Then they deleted everything....
-
The problem is that it results in an infinite loop, going right back to the first repeater.

467t/462r > 467r/462t > 462r/467t > 467r/462t So one radio needs to be in talk around mode. You would need a 3rd repeater to make it normal.

You want your antenna to match the frequencies you're transmitting on as closely as possible. 154/430Mhz is the common VHF/UHF split for a dual band HAM antenna. It won't have good SWR on GMRS since it isn't tuned for the 462/467 range needed for GMRS. It may work, but it won't work well. You want to look for a GMRS specific antenna like this one:
-
Interesting concept. Not exactly sure how it's accomplished with a single duplexer though, unless both sides (462&467) are full RXTX units. Either way, talk about long squelch tails and lag.

One of you should put up a large scale repeater if you want one for the area.

Nicely done - a huge improvement in group run communications! I helped our club migrate to GMRS a couple years ago and it was very well received. It is now a requirement for all club sanctioned events. We've got a thread detailing the change and the pros of GMRS, along with a rundown of our favorite and suggested gear to get folks started. I joke the radio is so you can hear good dad jokes on a long trip but we do a lot of training and guiding, so it really aids with instruction, direction, and safety. I can also run a separate channel on dual watch with the group and my tailgunner so we can talk logistics if need be.

How close to 462/467 must an antenna be to function? I have access to the antenna shown nearby. A friend ran into it and says, "Worthless label. 154/430Mhz. Made in China. About 6 feet tall. 58 cable with a BNC connector. Free to a good home." I'd use it (if it can work with GMRS) on a 15-20' mast with a DB25-G (25W) in a flat, wooded area. I'm not talking 5 x 9 perfection, just adequate to be heard and understood over a short distance, say < three miles. I know, I know, "Try it and find out." I hesitate to try it because 1) it might not work for GMRS and 2) as an apparent dual-band it might lure me into becoming a ham. What say the crowd?

Are 900mhz ISM radios dependable for e-com
PACNWComms replied to ULTRA2's topic in Equipment Reviews
Correction to above, 902-928 MHz. I like and still use some DTR410's, and even with the shorter fixed antennas, a mile range is still doable in the city. Comes in handy for my own use, and for monitoring the local vessels that still use them. Some have also purchased the newer DTR700 series radios, and left them defaulted on programming as they did with their DTR500/650's. -

Maybe, usually they are about $55-60 a pair with the goodies. When I got my first set it was $79 a pair.

A round pizza pan would be more aerodynamic

Thanks all.. I have recommended H-3's to others with good results, but two duds in a row, hmmm? This was a Amazon sale a while back for $19.99, and makes me wonder if someone was getting rid of duds. Maybe??

Has anyone tried to Daisy Chain two RT97L repeaters together as described on the Retevis web site? If so what settings did you use in the software?

That's why the majority of pilots will just put a mag mount on a cookie sheet in the window...

Yeah, it was just a joke. sorry. I was just visualizing a mag mount flying off a plane... must have been late last night when I was posting.

The belly fat one gets from the beer sticks around a lot longer.

At the last weekend's Two Rivers Off Road Club's 4x4 Blast, the Club made it official, they are moving from CB to GMRS. All of us on Saturday's run used GMRS and were impressed by the transmission clarity. There was a mix of HT's and mobiles.

I talk through repeaters that are 17 and 21 miles away so any little advantage I can get I'll take. The 3dBi gain of the Nagoya 771G helps a bit and keeps the conversation a bit more clear than the OEM antenna that comes with my H3. The length no longer bothers me since I've been using it for over a year now. Actually seem funny when I put the short Smiley antenna on it. But if you are only using it for HT to HT short range communications the OEM antennas are probably just fine. And that beer you buy with the money you could have put into antenna is gone in a half hour whereas the antenna should last you years. Buying rocks vs ice.

Like many have already started I have been through many different antennas when I was more active on the HAM side. I spent a lot of money on comet antennas and others. some were good, some maybe not so good. I learned my lesson, some antennas are better than OEM but it depends on the radio and how you are using them. When I started my GMRS journey I forgot the lesson I had learned with all of my HAM HTs. I now have a collection of GMRS antennas. I have determined that it depends on the radio and how you are using them. Amazing, I know. Actually the reason I was looking for different antennas with my GMRS radios was specifically to find a good flexible antenna that was at least as good on TX/RX as the OEM. I have 701s, 771s, Melowave Bandit Gs, a Smiley Slim Line, and even a Signal Stick cut for GMRS. All of them were tested on my KG-935G at specific distances in my mountain area. My big takeaway is nothing new; the longer antennas normally RX better when I'm on the ragged edge RX/TX. Anywhere else they all are about the same. With flexibility being my main desire I have a Smiley Slim line on my HT most of the time. If I am out in the mountains I carry a Melowave Bandit G in my pack in case I need the longer antenna. I haven't really had that need but it is easy to carry. I have found that the OEM antenna that came on my 925G is a very good antenna, but it is very stiff. The stiffer the antenna the more I am likely to catch it on something or poke my eye out again. Your experiences WILL vary.

This! Especially given what I use my GMRS HT's for, very short distance comms on the trail or around the spread or up at the cabin. Money spent on extra spendy fancy antennae is money better spent on boat cooler beer & ice! On the Amateur side of things, I so very rarely use an HT so it's pretty much a moot point, the rubber ducky that came with the radio is more than sufficient to get the farz I needs.
