Hi Bernie,
I've got a small Uniden hand held UHF. I use it when we go off road to chat with the other guys in the group. I thought about a permanent UHF install in my F100 4x4 and then later the Discovery but found the hand held unit was really convenient. You can use it in any vehicle, You can walk around with it too. I use it a lot at swap meets to chat with your friends in different areas, Let them know when you find a bargain they are looking for etc
They also have a hands free headset kit for the Uniden hand held which I thought was important in a Car. I thought it would be useful in a Cobra as you can't hear a speaker at speed.
It's 2 Watts so it has a bit more grunt than most of the hand helds. They are usually only about 600mW.
Uniden UH044
Cheers
