Right guys, I have located the aerial in what looks like a good spot in the loft and run the cable through the eves through one of the loft hatches into our bedroom. I've connected it to one of the TVs and the picture is very good indeed although I'm conscious that it's a much nicer day today and when the weather worsens it'll probably reduce a bit. I'm just going to try splitting the signal with a Y connector to the other TV in the room and see how much that affects the signal. I feel like progress is being made
