I have just finished running a coax cable under my floor, up the wall and through the ceiling to my bedroom to watch sky on my lcd in there. Prob I have is that the coax wont run audio, will it ? It will only carry picture ? - If so, anyway around this, or will I have to feed audio cables through also ? One final question, what connectors am I looking for to connect to the coax cable ends ? I think they are called 'F' connectors ? Not sure what to pick up but I'll be connecting it to my 2nd out on Receiver into Ariel socket on the tv.
