What should I do if I think my TV is being affected?
If you are responsible for your TV aerial, have received a postcard from us and experience new interference to Freeview, please contact us either by phone, email, via our website or by letter. We will assess whether the interference might be due to 4G at 800 MHz; for example, we will check whether a new mobile phone mast has recently been activated in your area. Or try our online diagnostic tool, which will help you work out whether 4G at 800 MHz might be the cause.
