Hi, I'm installing a freeview box (humax PVR-8000T) and I will need a 14 meter (45 feet) cable to reach the aerial socket on the other side of the room. The question is, is this too long and likely to degrade performance. If not, what kind of cable should I be looking for and any other advice greatly apreciated!! Can I get something from maplin? Thanks gents, Nick.
