The 4G providers have to guarantee to the government that 94% of homes can pick up the 4G signal in front room of the house ,so the signal has to be very strong to achieve these levels .
Most 4G filters block signals from 790 MHz on-wards .So if you still get problems with your reception after fitting a filter you may have to switch to a different television transmitter or move to Freesat or SKY as you may not be able to block the problem out.
To try and block the unwanted signals you
could use a 4G filter
