I am completely replacing my current CB, coax and radio. What I am wondering about is I am using just a part of a mirror antenna mount "aluminum" for my new antenna fixed to my aluminum tool box which is just behind the rear of the cab bolted to the upper rails of my bed of the truck. It's a Gull wing cross tool box,storage etc. The antenna mount is secured by four bolts and I am using one of the mounting bolts with a wire connector"2 awg" to the frame of the truck. Will this give me a proper ground?
