well, in order to be legal I recommend having one. I'm sure a lot of people use them with more than 3 watts and don't have a license.I think GMRS can go to 50 watt, but 99% are no more than 5 watt and they are typically different channels on the same radio. 1-14 FRS 15-22 GMRS. I have never met anyone who had a license
I would get something like this:We use basic FRS/GMRS radios without the detachable antennas but I agree that the antennas are crucial. What radios do you like?
I would get something like this:
It also does MURS too, which is license free, and in the VHF range so better for coverage.
Combine that with a roll-up j-pole antenna, and you'll have a pretty decent setup.
Get the DBJ-2 roll up (commercial version) from here: https://edsantennas.weebly.com/ that will work well on the MURS/GMRS frequencies and you'll be gold.
I have quite a few of Ed's antennas for ham bands, and they are excellent.
that doesn't make any sense cause a VHF radio doesn't work on the frequencies that the GMRS and FRS radio services work on.In my experience, living in coastal BC, they both suck. The trick is to get a VHF, and program both FRS and GMRS frequencies into it. I can talk to guys with walmart radios, but they often can't reach back to me if we don't have line of site.

VHF is 30mhz - 300mhz, UHF (where GMRS and FRS are) is 300-3000mhz, but specifically GMRS and FRS are around 462-467mhz.
If you need the best coverage and range, I highly recommend getting your ham license at least the tech, then you can use 2 meter band (144-148mhz) radios. Theres tons of them out there, with a upgraded antenna, and you'll have significantly better range especially when non-line of sight.
When you do have near light of sight though you can talk a long ways. I've made contacts on the 2 meter band further than 100 miles with my Kenwood hand held, a roll up j-pole antenna, and being on top of a 4800ft tall mountain
I hope what you're doing is legal...... it's important to protect the spectrum by operating within the rules. There's a lot of companies out there that would love to have the frequencies these radios and ham radios work on for themselves. They are a good resource that one can get for a cheap license and test.Check out the antenna farm online. I’ve dealt with them With good luck. Prices seemed pretty good to. We run vhf radios out hound hunting they seem pretty good. Icom and kenwood is what we have. But to be honest I don’t know what gmrs and frs is.
Another excellent point.
