Plus, don't finish the cable in a wall socket, the satellite boys won't use 
any cable that requires joints, instead leave a loose tail and finish it in 
an "f" connector.

Terminate your "universal" 75ohm tv cable in wall sockets, and they can use 
that for "magic eye" type connectors to feed remote tv's around the house. 
Basically wire all your 75ohm sockets in a star configuration.
