How can I get a filter?
If you believe the interference to Freeview might be due to 4G at 800 MHz, call us. We can either arrange for an at800 engineer to visit your home or send you a free filter to fit yourself.
The engineer will test whether 4G at 800 MHz is the cause of any disruption; and if it is, fit a filter to your TV system. The filter blocks the unwanted signal. You will not be charged for this service.
Alternatively, we can send you a free filter to fit yourself, free of charge. We have several different types of filters so would need to speak to you to understand which is the most appropriate one to send to you. Fitting instructions are included with the indoor filter and we can provide further advice online and by phone. We recommend you get an outdoor filter fitted by an aerial installer.
Please note, if mobile signals are not the cause of interference to Freeview, a filter won’t help resolve the issue.
