I have sky downstairs connected to a freeview equipped tv. I have a single coax cable running up to the loft and down into the bedroom tv with tvlink connected. This gives me sky upstairs with no issues. In the loft I now have two aerial connections doing nothing. Can I use any sort of device so I can get freeview on the TV downstairs and normal analogue tv upstairs whilst still maintaing th sky tvlink connection, and all with the single coax from downstairs to the loft ? Thanks.
