At the risk of cluttering up the "Tech Talk" section: The TV’s in our 94 Breakaway recently refused to work when switched to “Antenna” mode. I checked all of the connections and leads to the booster and the sets with no effect. I finally decided to take some “rabbit ears” from the house out to the coach to see if I could isolate the problem. When I got on the roof with the rabbit ears and connected where the antenna lead went to the head of the Winegard Batwing antenna, the TV sets worked fine. I took the head off and opened it up and found no obvious problem with any loose wires to the circuit board inside. I then took the Mechanical Engineer’s approach to the problem and called Camping World for a new replacement antenna head. Five days (and $55.) later it arrived, was installed quickly with two new pins and snap rings, and works good as new. Hope it lasts for at least 10 years like the original did!
