Thanks for all the info. We live in the Sierra foothills, and my wife and I like to do some 4-wheeling from time to time. We carry a cell and have a CB installed, but most of the time we are out of range of both. We were thinking of something that would let us contact a "base station" or hit a phone patch somehow in an emergency. I'll do some reasearch on the sites provided.

thanks again, OBG
