I have just been rewiring our house and have put a long length of CT100
cable (the stuff from B&Q) down from the loft to under the stairs, plus
further bits from under the stairs to where ever we might want the TV (and
the same for phone and network cabling) and was planning to join the
sections with coax plugs as required.

I was talking to a satellite system installer last week and he said you
could not have any joins in cable from a satellite dish. I really don't
want to hack off the new plaster to put in a single cable all the way down.
Is he right, or can it be joined?
