If you have a Tailgater type antenna, that most likely is the problem. Tailgaters rely on the reciever to power the antenna and the more connections between the reciever and the antenna the less likely it is to work. If you use an antenna like the Winegard G2+ that powers it'self the problems tend to go away.
