Hi, 'Sky' does require a particular hi quality coax which takes 'F' connectors. 'normal tv also needs good quality coax for later 'digi-tv' or if using set top digi-box instead of sat.
probs are need to keep mains & singal cables apart, and as no standard positioning of inlets on TV's how do you know where to run to?
Best way I have found is to run each to a flush metal back box, coil cables inside with blank plate temp. untill output connectors decided upon,
wiring in conduits to allow for the ones you forgot to go in later, [eg coax to dist box for other tv's ].
Sky doesn't work like Freeview, the satellite dish is connected to a digi box via a high quality coax cable. The digibox sits with your DVD player etc.
This is where it gets complicated though, you can connect to the tv using a RF (coax) cable, but to make the most of the plasma's picture quality, you should use scart leads from each item of equipment. Then of course if it is intended to view in HD, an HDMI cable link will be needed.
