Does anyone know; Does a CB antenna have to be grounded for it to work. I am hooking up duel antenna but my mirrors are plastic. I am tired of putting it on the roof.
Firestik sells NGP (No Ground Plane) antennae and you must also get their 18' dual coax ( 75 ohms ) designed to go with them. Get two of the tunable antennae, not fixed. Otherwise you might have to cut for length and that could go badly.
