I stopped my subscription to Sky a while ago, but still have the dish up and the pair of satellite leads coming out of the wall. However, my TV is Freesat ready, and I'd like to simply plug in the Sky dish to the back of it. First problem is that there are 2 Sky cables and only 1 cable input for Freesat at the back of the TV. Secondly, would simply plugging in the Sky dish into the Freesat input really be all I need to do??
