I have an old Sky digital reciever whose only current use is to prop up the dust in my loft. I was thinking setting it up in the bedroom as a secondary system. I heard somwhere you can get free to air channels but dont know how to go about it. I have a quad LNB in my dish so have 2 spare LNB's. I know I would need to run some high grade co-ax to it. Will it automaticly pickup the channels or would I have to contact Sky to get it activated?
