You need to turn the power button on for the antenna.

Very important point - if you have a powered antennae it work work unless turned on.
This assumes the OP has a Sensar antenna with an amplified head, which may not be the case as we're talking about an older 2002 trailer here that could have a non-amplified Sensar II on it.
I suppose some may consider this "splitting hairs" but many seem to refer to that wall plate as an "amplifier" or "booster" which it is not. Although Winegard refers to it as a power supply it's not really even that but rather a "power injector" because when you push that switch ON the only thing it's doing is routing the trailer's already existing 12 vdc to antenna head that does (in the case of the Sensar III and Sensar IV) contain a signal amplifier. If you want further signal amplification replace that wall plate "power injector" with a Winegard SensarPro which does amplify (or attenuate) the incoming signal.
The switch does one more thing, it physically switches between the antenna input and the outside cable connection. Some think that it only supplies power. That is why there is virtually no reception when the switch is in the wrong position.
