Unfortunately I have my HT on an exterior wall of my living room, which doesn't have a coax outlet. It would be very difficult to fish down a new line in this location. The nearest coax outlet is about 20ft on an adjacent wall. Currently, I have a wire running along the baseboard, loose. I plan on buying some plastic channel to put the coax cable in, this will help conceal it along the baseboard, but what are my option for the cable coming out of the coax plate ? Is there a special wall plate I can buy that connects to a plastic channel?
