Is distance from the dish to your tv a factor in determining signal strength/quality. My flat is quite far away from where the dish is positioned, so the cables must run a fair distance to my socket. Ive noticed that my signal quality bar is about two thirds full and the signal strength about a quarter. While ive not noticed any difference in picture quality, most of the time I cant get the digital radio stations and Channel 4+1 keeps breaking up. Would a signal booster help?
