Good info guy, thanks. I'm learning. Antenna theory is fascinating and mysterious. Smoke, mirrors and magic.
From what I've found looks like for gmrs, a disc of metal 6 - 8 inches works, doesn't even need to be a disc just the equivalent surface area if odd shaped.
Then I see 1/4 wave vs 1/2 wave etc. with no ground plane needed for 1/2 wave. I'm probably mixing disciplines here.
I'm getting a new truck but the camper will be the same. This photo is more up to date. I have three solar panels on the front now.
High on the roof would be ideal but I'm not sure practical with canoe. I may be able to mount a pole on the back of camper at roof height and mount there. This roof moves up and down so that would present a problem with needing coax slack and slapping in the wind.

Thanks for the rely.
The roof is fiberglass.
I wondered if I could mount someplace on truck but figured the camper and truck would block pattern.

Hello all,
Newbie here.
What are your opinions of these:
Wouxun KG-1000G
Midland MXT500
Midland MXT400
or should I be looking at something else?
Thanks, KVP

Thanks again guys.
The flagpole is fiberglass and collapses. It's only up when I'm parked someplace that gets a breeze, usually the beach.
I'm looking at getting gmrs to go along with my cb as an alternative when needed. Mobile use unless needed while stopped, so not really a base station.
What do you think about putting a pvc pipe on the back near flagpole that I could raise/lower a few feet for mobile/base use. Running the cable down the inside of pipe, under truck to cab and inside to radio. This would of course require a way to disconnect for when the camper comes off the truck.
Looking on line what are you thoughts here:
Just an arbitrary site I found via google
https://www.arcantenna.com/collections/gmrs-antennas-nmo-mounts
from that site, would this be a good choice?

looks like I'd need this to mount the above

other possibilities,

or this, not sure how it compares to the above.
