Thanks for reply
i'll print this off and give to the electrician, the main hub in the living room has 4 coaxial cables poking out with no faceplate attached yet and the main telephone point in the hall has lots of wires hanging out - need to check but i think each individual wire has 4 coloured internal wires (all covered with a white plastic cable cover) which i am told will be left open until BT arrive on 3rd Sept.
Will this enable me to transmit hd signals or will I have to just send sd signals via the coaxial?
