My neighbours and I have been experiencing strength fluctuations for at least a couple of weeks now, resulting in channel losses and poor signal . One day everything is fine. The next day the majority of are poor or gone.

We all have based aerials and have never had any problems before. What is going on?

Neil Garrod:

I can't find any reports of problems at present, and there's been no Planned Maintenance this week.
Have you had problems this week? Or has it just been in previous weeks? There might have been Planned in previous weeks but I can't confirm that one way or another.

If you and your neighbours continue to have problems, ring the Advice line on 0808-100-0288, or if you have atwitter account @FreeviewAdvice
