There are a few of us around here that prefer the Wilson "Lil' Will" magnetic mount...while others like the "Firestick". (can't remember manufacturer)

I zip tied my wire to the roof rack, over to the door jamb, down behind the weatherstripping, & under my floor mat to the CB. (mounted on the pass. side of the hump)

If you search, I remember seeing links to all kinds of info on the subject.

Also, a trip to the nearest truck stop will reveal a pretty good cross section of what's available.
