Home TV and cable setup

[bailda]

Does anyone know of a good website or otherwise that could advise on how to wire up my home in the best way with the best signal going around to all of my TV's (I currently have 7) as I have kept adding new bits of cable over the years as I added a new tv to a room and the piucture isn't that good anymore.
I currently have Sky+ and analog NTL cable feeds and 3 different boosters in the chain at different points.

Thanks in advance

I don't know about NTL cable but ordinary analogue TV and Sky can be simplified by using a Loft Box.
