TV aerial issues

[[TW]Fox]

Hi chaps,

Just moved into a new build and the developer has helpfully left a coil of coax in the loft for the TV aerial connection. I've wired it up a proper aerial I picked up at toolstation. The coil of wire contains just one lead - I queried this as I expected to see a lead from each aerial point which I'd then connect into a signal splitter or similar but apparently not, it comes like this.

Well, it doesn't quite work. The upstairs TV point yields a full complement of channels. The lounge TV point does not - I get about 9 freeview channels.

I have a second downstairs point in the dining room which works perfectly as well - its just the lounge one that doesn't.

Any ideas?

It might be worth checking the connection in the one which isn't if you are confident enough to unscrew and take a look? Is it just a single aerial output or does it have sky connections etc. on it too?

You've definitely not got any of the outer foil/wire touching the inner sold core

So I've had the face plates off and this is exactly what is going on - where the cable terminates into the faceplate its touching the outer foil in numerous places. Furthermore, the worst of the sockets in the lounge is at a 90 degree angle and has at one point been bent back on itself - would this have damaged it?

A common theme with larger housing developments is that it’s the electrical contractor doing the aerial cabling work. They’re rarely experts in this field, and so often use the lowest priced materials and hand off the physical work to the least qualified spark on-site - the junior or the apprentice – because the work doesn’t need to pass the same safety tests as for mains and lighting circuits.

That would explain why presumably the same guy wired all my ethernet ports in series

Nightmare! Can that be rectified without completely new cable runs?

It took them a day to come back and do exactly that, so it does all work now thankfully. But it's amazing isn't it?
