I know this has been asked before however my husband is having trouble with BBC channels. They start off being fine but after a couple of minutes the picture becomes mosaic-like.
He's tried retuning it and ends up with all the BBC channels coming from Wales, which isn't too bad but it's not what he wants.
What does he need to do to get a clear signal please?
The house is in the CH43 area not too far from Bidston Hill
/ Upton Rd.
We have just a basic aerial that was installed a couple of weeks ago no Sky or Virgin etc.
