Hello STW

I'm running a coax cable from the Sky HD box upstairs to the HD TV downstairs. Cable was already laid behind the walls when we moved in. Problem is, the picture quality is a bit meh. Like watching council telly in the olden days.

Is coaxial cable actually capable of giving HD-quality images? Or is the poor quality a symptom of a long cable (15-20m maybe?) or poor connectors at either end?

Cheers

B

Well HD digital can come down from a roof top ariel/satelitle signal via a coax cable so I think it's possible. I forget how our 2 box system when we had sky was was setup, it was either two cables out of the satelite or one from the main box to the secondary one. Perhaps the key with our setup is we had two sky boxes, maybe the sky box doesn't oush out enough of a stron signal to carry over the long coax, given the Sky contract I had was based on 1 tv in the room for each box it's possible they deliberately spec the box to ensure you can't run long cables ?

Have you got one of those "magic eye" things on it?

I'm guessing the Sky box is just feeding an analogue signal to the TV downstairs via the coax. That will be why it looks rubbish.

It's not the cable at issue. Coax feeds sat and cable decoder boxes with digital signals including HD.

What you want is to have that coax attached to a second output on the dish itself, not from the Sky box, and the TV downstairs then needs a second sat box or a freesat box or maybe it has a sat input on the TV itself (a few do). Though only the second sat box from Sky will give you all the Sky channels, and that will cost you an a second box fee. If you don't mind only the freesat channels then you can do that without the fee.
