4G may give problems to FREEVIEW channels

4G may give problems to FREEVIEW channels
if you are having problems when 4g launches you will need a filter for the tv aerial to fix the problem

Both 4G mobile services and digital TV use parts of the radio spectrum,
that is bands of frequencies, to reach us. The 800 MHz frequencies used
by some 4G services are next to the frequencies used for Freeview.
TVs and set-top boxes that receive Freeview may have the TV service
blocked by these 4G signals; there is a very small chance this may
cause disruption to your Freeview service.
You are more likely be affected if you live close to a new 4G mast,
are in an area with weak digital television reception or have a TV
signal booster.
