I have a 2007 Jayco Seneca 35 GS with an entertainment center I have all the cable hooked up and I get an air antenna signal no problem but I can't figure out how the cable connector comes into the RVwhat I mean by that is everything is fine at the campground box on to the into the RV but can't get a signal or program auto program to get the cable channels it looks like everything goes through the amplifier any suggestions
