My signal was very bad yesterday afternoon during the storms on Channel 4 mainly, in fact the slightest gust of wind makes me lose my signal. Is it a problem with the aerial being a bit loose and do I need the TV man? In the end I had to watch analogue.
This is a common problem where trees are between you and trhe signal. Sometimes repositioning the aerial can cure the problem ( or make it worse ). The only other answer is to change over to satilite reception . You would need to get a Freesat box and a dish or if you are willing to pay switch over to SKY.
