Sorry if these questions have already been covered before.
Firstly I had NTL come round to install an analogue TV service box to my flat in London, however the cable access point into flat was long way from living room with TV, so instead of drilling through a bunch of walls, and laying cable everywhere, I thought if I get a
AEI DIGISENDER-GOLD box from Argos I could just have the NTL TV signal sent to living room via wireless.
Is this a bad idea? 
(most people seem concerned with getting second signal via wireless rather than just getting the original one to the TV in the first place)
Secondly does anyone know when Battersea in London is going to get digital rather than analogue service?
Finally does AEI Digisender signals cause interference to either G or B wireless LAN for PC's?
Kind regards
