I think I can answer this one because I'm very proud of being able to do it myself recently! I have Sky and have a cable running out of RF2 outlet in the back of the box up in to a booster in the attic. It goes in to the UHF feed and the RTE aerial goes in to the VHF feed. All my TV points are then attached to the outlets on the booster. I've tuned in a channel on my TVs so that I can watch whatever is on my Sky box in any room in the house through the ordinary RTE aerial connection. I also installed a Remote Eye in the bedroom so I can change the channels from there, otherwise I can just watch what's tuned in on the SKY Box at the time in any other room. In order to get the Remote Eye to work I had to buy a bypass kit for about €14 as the signal can't pass through the booster so the Remote Eye gadget is connected in to the UHF point and the bypass kit is connected in outlet in the booster which feeds the TV point in the bedroom. Hope this answers your question, it's a bit long-winded!
