Hi, please help, if possible. Have a Roadster TFT TV/Monitor. Would like to use it in my roof room, where there is a wall plug from sat dish on roof. Wall plug has two "normal" ant connections each side and threaded ( I guess coaxial ) connection in middle. Roadster TV has one socket ( male ) with earth sign ( kind of little tree ) next to it and one socket ( female ) with "ant" next to it. How do I connect up? Can I direct? If so how? coax only? or ant only? or both? Or must I go through sat receiver? In that case I guess coax from socket to LNB IN on Sat receiver and ant cable from LNB OUT from sat receiver to TV "ant" socket? But is that enough? Grateful for help.
