This could easily be 4 sites here plus the PC in the office. Do I really
need 18 separate cables?

I would run a satellite cable (75ohm quality coax) to everywhere you
will need TV/radio/satellite, or, if you use both terrestrial AND
satellite, two. You can mux both signals down it - and indeed FM radio
- but its hard work.

Then add at least one cat 5 cable.
In extremis, you can add local switches to get more ports on the cat 5,
and if that's gigabit back to the main hub, having several;
conversations down one cable shouldn't slow you down much


The satellite/TV/radio cables you feed from a distribution amp. I had
one that happily took a VHF aerial and TV aerial and fed about 12
cables to the house wiring.

It proved to be reasonably possible to do evil things with the coax,
like dasy chaining sockets off it for 'TV here...FM tuner there'
without it being too bad on reflection, mainly because the distribution
amp at least provided proper termination.

You can run tow 100Mnps channels down one CAT5 cable or one 100Mbps and
a phone...but its a bodge.

Wire is cheap, so lay in plenty. The big problem is then what to do
with unused bits. Sometimes leaving them coiled up in the back box is
sane. Or if you have hollow stud walls, coiled up in there.

Document everything.

No satellite here yet. It may come as the new house is in a less good
location for London terrestrial.

OK chaps. That is plenty for now. I'll come back for more detail when we
get around to second fix. (could be 9 months!)

Thanks
