I moved into this flat a couple of years ago. At the time of looking around pre-purchase I noted the amount of cables coming in through (well, past) the windows but forgot to ask the previous occupant about them. They're terminated in a mixture of Belling-Lee and F connectors and are, of course, all unlabelled.
In the bedroom I have two downleads ending in Belling-Lee which both carry what seems to be a good aerial signal. At least I can plug either into a STB and get a good signal and all the muxes and channels. (Why would someone have two aerials into one room?) One is at one end of the bay, the other's at t'other.
I haven't yet gone out to look at the aerials on the roof. Will need a pair of binocs, I think - they're on a tall Victorian semi which is built-up on a high surface.
The installation appears to be of good workmanship - the downleads are CT100 cable (marked "Eagle 100U coaxial cable") with braid and foil. The cables are terminated in metal screw-on Belling-Lee connectors.
Unfortunately I made a a mistake in tugging on the cable instead of the connector and predictably it pulled out of the connector body. When I come to re-fit it, is it usual to screw the connector body onto the cable outer, or just on the inner plastic core/foil/braid mix up to where the outer insulation's been cut away?
