I have purchased a 2 socket wall plate. It is a maxview satellite/UHF socket. Inside is a clamp that covers both sockets and a metal loop for what I presume is for an earth wire. I have put a metal wall socket base into the wall. I already have the UHF TV coaxial wired up and this works ok. Before I snip the satellite cable(!) do I simply clamp in the satellite, does it matter that the outer wire mesh on the coaxials are effectively joined? Each socket has an insulated clamp for the inner wire. Thanks in advance of any advice Do I need to wire the earthing loop to anything?
