I installed a CB antenna and Bearcat CB today. I'll also be installing a Midland MXT275 GMRS radio, when it comes available, which should be soon. GMRS is far superior to CB, but most folks with whom I hit the trails have CB's, plus, I like to sometimes chat with truckers on road trips. Anyway, here are some shots of the set-up. Glad to have this done. The Bearcat is a CMX 760. I'll have to tune it, as they supposedly only put out 3 to 3.5 watts of power. It can be tuned to give the full 4 watts, so that's on the to-do list. Anyway, the GMRS will have far greater range, especially with a good antenna, and you can give handhelds to buddies who don't have any comm devices.
GMRS are good and nice to have when not in the vehicle, too. Also there's the 2 M (?) HAM or Amateur radio set ups. But neither of those give you the ability to communicate with truckers or other general users on the road. CB still existss as a viable means of communications.
