First off thank you all in advance. Also I am an old broad that is quite tech savvy but don't understand some of the lingo (ie "Streaming") To my query. I have an LG 42 HDTV with a Shaw gateway system therefore I have a portal on top of my TV. I want to move my TV to the other side of the room & would love to avoid running 50' of cable coax around the room. Do any of you know of any transmitter receiver units that will accept standard cable coax? As I live in a RV Trailer the last choice solution will be to drill small holes in the floor & past the cable underneath the trailer.
