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.
If it has, we can send you a filter to fit yourself, free of charge. Full instructions are included and we can provide further advice online and by phone. In most instances, fitting the filter will resolve any interference from 4G at 800 MHz. If it does not resolve the interference and, if you are eligible, we may be able to arrange for an at800 engineer to visit your home, at no cost. The engineer will test whether 4G at 800 MHz is the cause of any interference; and if it is, fit an at800-approved filter to your TV system. This blocks 4G mobile signals and enables you to continue receiving and watching Freeview as normal.
If during the engineer’s visit it is established the interference to Freeview is not due to 4G at 800 MHz, the engineer can provide advice on how to retune your TV or fix other common causes of interference. The engineer will also fit an at800-approved filter to prevent any interference if new 4G at 800 MHz masts are activated in your area in the future.
