Who's going to travel 200 miles to install a TV aerial?

Some years ago, I came across a distribution system for some sheltered
housing in Farnborough which was maintained by a firm in Newxcatle upon
Tyne.


Yes, some years ago there was a Newcastle firm that had contracts with
property management firms and housing associations all over the UK. I
don't remember the name. They tended to send their own electricians (who
were electricians pure and simple) to fix problems with TV distribution
systems. They also used them to install CCTV. These guys routinely
fitted a modulator in line with the TV aerial downlead (for the door
camera), with no concept of channel clashes, signal levels, etc.
Eventually the Newcastle firms would send for a local aerial guy,
presumably taking pot luck in the Yellow Pages.
