Certainly better than just an HT inside of a trailer.My thought was to have a handheld inside the trailer with an antenna on top, I would assume that a longer antenna would help, and I figured if it was on top of the trailer I'm getting an extra 10 foot elevation. I realize that it's still line of sight, but any advantage I could get. Even if I'm outside the trailer, I usually am no further than 10-15 feet away, so with volume up I would hear it. Why use a handheld? Because somehow I ended up with 3 of them, I'm basically cheap. And, the amount of time I would use the mobile in the trailer would only be to monitor her.
I've looked for repeaters up there, nada. When we leave next month for NC, I will def be mapping them out for where we camp down there.
One phone app I've found is alltrails dot com, very handy! You can do a search in the area you're going to be in, and it shows trails that others have already gps'd (is that a word?) and saved. Gives you distance, how hard a trail, elevation changes etc.. You can download the trail map that they saved to the phone, and then it will use your phone's gps to track you. Never thought about it, but even with no cell service, the gps is still working.
Although, 5 watts is a bit low. Anytone 779uv/db20g are like $80-90. Tiny, can run off a cigarette lighter poet and 20watts to boot.
Food for thought. From my house to about 3/4 of a mile to a shopping center (through trees and past houses hill top to hill top) hts can not make it. But the db20g/at779uv at 20w with a roll up slim jim, n9tax gmrs, (inside the house inside of pvc wiring track) makes it clearly to the ht back and forth. The antenna tip is about 20-30 feet off the ground in the kitchen attrium.
Most cellphone will use sat for gps and augmented cellular towers to make it more accurate. The newer phones seem to rely mostly on the cellular location services. Part of the reason I suggested something like a garmin inreach. Short text messages regardless of cellular data. Small and compact with the availability of larger units with maps. If there are questions ask mmarc, he uses them for offroading.
All trail app is nice.

He/she didn't mention anything about a repeater. But it was on those lines of thoughts. I mean when we camp, although I want to be in the trailer next to a radio. That rarely happens. Gotta cook, tend to fires or sit outside with the brew and mellow.It sounded like he and she might both be outside of the trailer with their handheld radios and he wants to be able to reach her.

Me personally. I would mount a harbor freight telescoping flag pole to the trailer side, it extends 25 feet.
Then mount something like Fong jpole to the top lmr400 flex co-ax. Have a patch pass through into the trailer with a jumper coax to a mobile radio ( lets me have extra power if needed) in an ammo can, make so I can disconnect outside of the trailer for storage. As well as, have extra spooled cable for when I disconnect the and connect extra cable outside and move the ammo can outside. Power would be provided by something like a jackery aux power supply. That way I am not tethered to the trailer. Could even use an rt95 repeater in this kinda setup extending some range.
Point of this setup is to get the antenna as high up as possible.
Frankly, I just sling a slimjim roll up into a tree and get something of the same effect.
Have you thought about something like a meshtastic or garmin reach? Might be cheaper although it is not voice.
Going to depend on range, terrain, and budget. Ht to ht (realistically max a couple of miles through vegetation) is not going to go far. VHF service like MURS might get further. If you had a repeater where the antenna was 100 feet up different story.
You didn't mention what the TT (travel trailer) is nor other specifics.

Yup like 1/4 wave said.
You should be fine.

What kinda of distance are you talking about?I am putting a repeater that has other repeaters close by. One transmits on 461mhz and the othe other on 463mhz.
I intend to use grms 462.725 TX and 467.725 RX. Should I have any problems with this? The antennas are not that close to each other

Except most radios (actually I think all) are not tested by the fcc. But rather a third party testing house. Don't believe start pulling the FCC certs and look at who signed the certification testing.

Pennsylvania state senate passed a bill to disallow mobile usage. Some wording was changed to disallow mobile radio usage aimed at amateur radio.
If the governor signs this bill with the wording. You as a gmrs/cb user will not be able to legally use your mobile radio on the road. This excludes public safety and commercial operators like taxi cabs.
REDDIT POST with the information.

That is mighty nice of you. I mean it's not like the cost to get a pair is super expensive.I totally agree. That way the system users can operate under the system license authority and don't have to worry about getting an individual license.
I have several Part 90 Business Radio Service frequency pairs licensed statewide in California and if I need to I will give permission and/or give up a pair for his system.
But most administrators off the bat would of not offered or put secondary user stipulations even the if pair wasn't used. You know "in case".

Unfortunately, most government radio admins want to play God.
I wonder if it was the county council that enforced the requirement or each depth voiced they wanted that requirement added.
Either case, it's the people that won. On the next county over I often hit dead spots with their system.
It's funny to see in other counties every one running multiple high gain antennas. Where in moco almost all the vehicles are running low gain antennas, minus the few exceptions.

Around here (montgomery county maryland). Local municipality set up the radio system properly. Public service network on 800mhz. They could of gone with lesser equipment and use higher gain antenna. But chose to go with a mandate that required 98% coverage of the county with an ht. Yes this included in people's basements and in parking garages.Yes, you are in my head. We all now gmrs will probably end up in the trash heap because of all the repeaters and cross talk making it unusable. So solutions for when that happens it what LoRa and other avenues are for. Keeping an open mind on solution that can make this work. We are trying to create a redundant and super resilient system for community members to communicate with each other as well as create a direct line from agency support to the community. We all know people are busy and we have to minimize the impact this may have on their lives so we try to make it approachable. Gmrs is easy to license and allows the use of repeaters. Pretty cool . Of course we have blended amateur(ACS) ,ARES , smoke signals and everything else into the mix to accommodate each community and their way of wanting g to do things. We are here to try and minimize the gmrs jamb up or frequency overlap from other repeaters and users. So we have thought of securing a couple frequencies for this and some how making it license free or easy to get for the public. I will eventually sit down with the FCC and discuss. They have reached out and asked us for solutions to Tubbs, Maui etc.

What they needed up with was a 2 site simulcast system. It is one of the best systems in the country. I have used the harris xg100m and a g5 unification in some absurd locations with the ability to listen to the county radios.
Either case, the state police use part of this system as well as many other agencies. Each pretty much has their own main talkgroup and tac channels. This includes the cert (was react) teams.
But it took a lot of handshakes and negotiating from multiple people to get it the way it is. But as a public safety group you might be able to get the local council, pd, fd and ems onboard to get you some talkgroups and interop group channels. Hell they probably have some old xts2.5/3k/5k. Hell 700/800 Mhz Motorola gear are dirt cheap compared to the vhf/uhf r1 counter pars. Think like $60-80 vs 200-500 for a unit.

If we are discussing simulcast, and lora back bones/ radio.
Why is the group not talking to the local pd. Who probably has simulcast already set up. Old gear that can be repurposed, get potential federal grants and be administered ( really only sounds like you need 1-2 tac groups). As well as the license for the extra frequencies. Probably can be encrypted as well.

Gmrs 18 should be simplex.
Rept 18 should be the repeater pair. Which is what you should be using to try communication with a repeater.
Well that is how most radios are set from the factory.
So radio to radio it should be on gmrs 18.
The map view of the map on this site is not very good when it comes to repeater footprint. Well hell accurately measuring footprint kinda sucks to begin with. I would kinda ignore it.
Do you have the proper tones set? Where you trying inside of a car?
If in doubt get as close to the repeater as as you can and high as you can. Try again at that point.

Agreed. It's been on the market for what a year? Maybe there were no offers that came close to what they wanted.They would seem to be a reasonable suitor, but if such interest were ever expressed MFJ’s announcement would seem to imply that it is unlikely.

Thought it was a rumor on reddit.
They have been trying to sell. I really thought dxenginnering was going to pick them up.

If the repeate comes up and you still can't make it. Might be worth finding a high peak closer to the repeater. Especially, with a ht.So I have the Encode set correctly at D423N as shown in the original post. Ok, I'll keep working on it.
Interestingly, this repeater has been down for 4 days, Not a peep on that channel.
Not all repeaters are created equal.

You do not have to have a tone on receive. Since the tones block incomming messages that don't have matching tones. You would hear it if no tones are set on your radio, even if they have tones enabled.
If you don't have tones on receive you will hear all transmissions on that frequency.
No tones on encode shouldn't not be done (most repeaters have tones on input). So that it will ignore and not repeat any transmission that don't have matching tones.
To complicate things more, there is cross repeater talk as well as repeaters with multiple tones.

Shouldn't 2 different frequency segments. Guess you are going to have to send it and find out.
But not 100% since non adjacent frequencies can still wipe each other out with enough power, suppression of harmonics. Especially, with antennas less then 1/2 wave length away (longest wavelength/ frequency).

For my 70cm gmrs hts. I usually use what is supplied with them. Aka my motorola xts5ks.
For my ham radios (2m/70cm/aprs and gmrs) I have found stocks antennas are ok. But the stock rubber duck antennas did the best job trying go across such a wide bandwidth. Even the signal stick was barely an improvement on the 878uv, caused intermod issued with the Feng bf8hp for me at least.
For my gmrs hts I usually swap them for Nagoya 701c and they perform admirably.
The harris xg100m. The long high gain antenna works the best. It's tri band and is adequate.
Real short, stock rubber ducks work fine. If it is a gmrs specific ht. I found the Nagoya 701c a good antenna.

What kind of antenna should I put on my travel trailer?
