The problem is, while your local RV dealer does not get your trust, neither are you competent to diag your problem. You are a Parts changer, not a Tech. Winegard wall plates NEVER fail unless there is a short in the Coax system connected to it(Based on my 40 years as a tech and still working). If you are connecting just the 2 power wires to the wall plate(NO coax connected) and there is a short, you are doing something wrong. If you connect the Coax and it shorts, there is a short in that coax going to the TV antenna head. Now, when this happens, disconnect the coax from the Antenna head, if the short remains, your coax is shorted somewhere. If the short goes away the Antenna head is defective. This assumes you are connecting the ANTENNA part of the wall plate to the roof top antenna. Doug
Don't blame a product when you have no idea how to fix the problem.
