Can anyone confirm that a quadruplex outlet takes just one decent screened satellite cable?I am doing a lot of electrical and cctv work on a house, and the customer would like sky+ multi room as well as watching cctv in every room. I have seen a labgear splitter that accepts sky+, DAB, DTV, ATV and CCTV with just one output to each TV. It just seems a lot for one coax/satellite cable to handle.
Most of the time, no. A quadruplex outlet takes two cables.
It all depends what your combining at the front end of the cable run, and then splitting at the outlet though. It can be possible to have one cable running sky, dtv, fm, dab, cctv etc as they are all on different frequencies. And decent double copper screened (eg PF100) cable can be quite happy with it. Don't forget it's all RF, mono though after being distributed. It can be easy to have too strong a signal if you're not careful. If they want HD quality then you'll need to get into cat6 wiring and hmdi doodahs and more i think!
However standard quadplex outlets have sat 1, tv and fm, and sat 2. Sat 2 is for sky plus and so needs a separate cable. Further to that, if you're planning a loft box like the labgear, you'll need a third cable from the main location (lounge?) to the loft box as a 'return' cable. I think for multiroom stuff you'll be looking at 4 coax cables to each main point, based on the diagrams from the link below.

CyberSelect | Labgear TV distribution amplifiers is quite good at explaining it as well. If you google 'Bill Wright Aerials' then you'll find a raft of knowledge on the home coax wiring ways.
I've been learning a fair bit lately from all the online sources I can! I'd definitely second kerching on using an aerial specialist for the on roof part though. And even to cast an eye over all your work. So long as you use the proper cable, and install it properly, the tv guys should be ok working with you.
I've just fitted an HDU681 with FM, UHF aerial, and two Sky inputs, going to/from one main location and splitting to four other outputs. (room for expansion!). Magic eyes (
