Will 4G affect TV received through satellite or cable?
Because cable and satellite TV do not use Ultra High Frequencies known as ‘UHF’ to provide their services and as they’re not received through a standard UHF aerial it is highly unlikely that 800 MHz frequencies will cause interference to either of these services.
If you watch cable or satellite at your property but also watch Freeview, TV received through an aerial on another TV set, you can request a free filter from us which will prevent potential 4G interference on Freeview.
