Ok, Here is the sitrep! Putting CB/WB radio in the camper. It's a Lance slide in, mounted on my goose-neck trailer. I have mounted the CB already in the camper. I purchased a Zero Ground Plane Antenna by Solarcon, did a bunch of research on this antenna, most of the RV guys are using this because of the lack of ground plane, and a specialty Marine Antenna Mount. So here is the question for you guys. The roof of the Lance/camper has a 20 GA Aluminum sheet roof over the complete roof, does this aluminum roof create the ground plane for a normal CB antenna. More specifically, does aluminum work the same as steel as the ground plane. Everywhere I research, it states Steel as the ground plane, but can't find anything the Aluminum is the same or does create the ground plane. Give me your input on this. I'm very interested in what you guys say, as I have gotten many mixed signals on this. Post up.
