We have ntl digital, but don't have a box upstairs where there used to be an analogue box. The socket is still on the wall though. With the digital box i see some sort of splitter that sends one cable to NTL digibox and another which gives me a regular rf output. Is it possible to get a cable to connect direct from the socket to a tv in that room (this is just for the purposes of getting regular terrestrial channels [1 to 5] on the tv there), or do you have to have a cable box in place to deliver the signal. If possible will it be ok to use or will it cause problems with NTL?
