Notice the vertical antenna on the truck.
I believe this first antenna is referred to as a "dipole", mounted vertically. CB to coax, coax to antenna.
The shell of the truck is fiberglass. Even the front bumper is plastic. Of course there is metal; door frames and the frame itself. The shell is also dipped in a rust proofing solution and I had to clean out threads in the truck that the screws go in. So the screws tap into metal instead of the coating from the rust proofing. I also grounded the mounts that I installed on the truck.
Below, you'll notice the second antenna I mounted horizontally making what looks like a very skinny and upside down capital "T". It's only mounted there, the second antenna isn't wired to the radio or the first antenna.
Will this setup work? Will this create the needed reflective element?
