Thanks for all of your replies. I'm starting to get a much better understanding of home installations.
The house will be cabled for Virgin Media.
The client wants 7 T.V points. I have had mixed answers on how this should be done.
For a HD TV Virgin system, should i ;
1) run one or two CT100 cables to each screen location? (where a box will be)
2) run the CT100 cable(s) from the Virgin HUB location to each screen location?
3) run the CT100 cable(s) from the HUB to the first screen location, then another CT100 cable(s) to the next screen location, then on to the next screen location and so on?
How many HD TV or Standard TV boxes can you have on at the same time?
I will be leaving a access channel from the roof top to the HUB location for a possible future SKY system as suggested.
Will a Virgin broadband Wireless HUB cover a 4 story house? if not, is it a simple matter of just running a CAT 6 cable from the wireless broadband HUB to another location and pugging another wireless HUB there?
Thanks for your help.
