I have a long loft aerial which seems to give a good signal, and old brown co-ax plastered into the walls, but from the wall socket to the TV I have some kind of 2-metre connector lead, probably bought from a high street shop, which seems to pixelate on some channels if there is a power flex close to it.
What spec of cable should I look for that might be better?
