Help is at hand for TV watchers in Attleborough facing interference since 4G mobile services were introduced to the town earlier this year.

4G, which is transmitted at 800MHz, can cause loss of sound, pictures going blocky, freezing and 'no signal' messages when watching Freeview. However the firm at800, which was set up under government direction, can offer support for residents with interference problems.

Ben Roome, at800 chief executive, said: 'If you rely on Freeview for TV, we can arrange for one of our accredited engineers to visit homes to fix Freeview interference caused by 4G signals, free of charge.

'If you use Freeview alongside other TV services, we can send free filters which block mobile signals that are easy to fit to the aerial lead connecting to TVs and set-top boxes.'

At800 offers extra support for pensioners. For more information call 0808 1313800 or visit www.at800.tv
