Can anyone help please. I'm losing reception on HD channels. This started last week and there was a couple of comments about high pressure. There is still high pressure but surprised there are few comments about reception. As such wondering if its my equipment. There are some confusing statements about Sandy Heath transmitter. This web site suggests possible weak signal, but this is not mirrored on the BBC or Freeview web site! I live near Cambridge.

Coach:

Many people in the southern part of the UK had reported reception problems and most now have normal reception as the weather pattern resulting in the temperature inversion is moving away from the UK.

The phenomen are entirely natural and there is nothing anyone can do to prevent the effects disrupting reception of TV signals and others. Now that the strong storm is affecting parts of the UK, appearing to be mainly up the western side (hence storm/flood warnings in Cumbria and Lancashire) the high pressure effect should now be diminishing.

Did you try a retune during the high pressure period? If so you will need to do a retune to recover the services lost by that retune. Note though that there was reported engineering on Wednesday but I have no knowledge of when/if that is completed.
