Many thanks.
Just checked the specs on my new TV, and I think it also has unicable (only want it as an emergency backup should the sat box fail)
Googling EN50494 it appears this is unicable.(Satellite input)
• Connections for terrestrial/cable andsatellite. Connection steps: SUB. t MAINt Antenna
• For SUB. jack, connect only when you areusing twin tuner mode except for SingleCable Distribution EN50494.
Will read your unicable link now.
Many thanks
