If I connect my 19" flat panel TV to the booster (rear of the RV) I will recieve 15 channels. When I take the same TV and connect it to the output in my bedroom (fifth wheel) I only get 2 channels. Once in a while a couple others will come on but the signal strength is too low 95% of the time. My first thought was the cable buried in the walls was bad, so I bypassed it and used a 25' coaxial cable I had made by my DirectTv guy. If I connect this to the booster, the same thing happens, 2 channels. So my thought is a weak booster, What do you think?? It works fine using a 3 foot coaxial cable connected to the booster, but when I replace that one with a 25' cable, I have weak signal problems. All suggestions are appreciated.
