Can anyone give me some help and advice on installing a coaxial socket upstairs. I live in Milton Keynes where all tv signals are distrubuted from a main aerial through underground cables to all houses. I have a UHF & FM socket downstairs in the lounge, and want to install one directly upstairs in the bedroom. I've searched the net and can't find a splitter box that will change/split the box downstairs and allow me to run a cable upstairs to the new box. What's the best way of doing this?
