Info received from a village resident. Are you experiencing similar issues?
Over a few months, I have been having trouble with the TV reception from around 5 pm to approx 7 pm, it meant missing the end of programmes or half of them, the TV would become pixilated or I would lose the signal altogether,
I eventually called Freeview who asked me to unplug the Arial re-programme the TV, plug the Arial in again and repeat the operation which I did, this did not resolve the problem.
They then gave me a number to ring 0808 1313 800 which is a G4 contact Number, following conversation they sent me two filters to fit one as the Arial enters the house and the other just before the TV, I did this and left it a couple of weeks to monitor the situation, the problem returned.
