We are going on a long trek next summer so I am putting in a CB radio to communicate with the other RV's. We have a 2008 Fleetwood Providence 40X and back of the center storage rack between the front seats there is an access area. In that area there is a CB antenna cable does anyone know if this goes to an actual antenna or is there an attachment on the roof for an antenna? I have been on the roof several times and haven't noticed anything that looks like a CB antenna. Any help would be appreciated.
