Hi. I was about to order some tv aerial coax (about 25m) to add an extra aerial point in the house. I just realised though that I might be able to use a Sky cable that is already there. It would save me a lot of work as the cable is hidden and is in the right place. Could I just connect it to the tv aerial? Obviously I know that I would require different connectors. I've got twin Sky cable which is about 8 years old.
