Are digital aerial leads different to analogue ones? I have telewest digital tv. The aerial lead from the wall socket to the digibox is very short and I would like to extend it. It costs £25 to get a technician out so to save some cash I want to do it myself but am not sure what sort of cable to use. I understand that as long as the digibox is switched off when I do the work there should be no problem - unless anyone knows different?
