I'm going to swap out the OEM radio head for an Aquatic AV, after Christmas. The question is removing the the OEM also eliminates the CB thank goodness. Now I have an extra Antenna on the tour pack, years ago there were a lot of people using twin antennas. The real concern is would both connected make for a better signal I have ZERO knowledge of these sorts of things Help. Radio reception in the communist run state of Pennsylvania is not the best anyway. Fred
