NEW fourth generation mobile services, known as 4G, have been switched on in Catterick Garrison - and there is a chance they could cause interference to Freeview TV.

Because 4G at 800 MHz signals sit next to the frequencies used by Freeview, they can overload the receivers in TVs and set-top boxes causing interference such as loss of sound, pictures going blocky, freezing or the TV screen going blank or showing a "No Signal" message.

However a company set up at the Government's direction, at800, offers free support to households that rely on Freeview for their TV

Chief executive Ben Roome, said: “We want to ensure that people know it’s our role to fix Freeview interference caused by 4G at 800 MHz, and there’s no charge for our service.

“If you rely on Freeview for TV, we can send you a filter, free of charge, which fits into the aerial lead connecting to TVs and set-top boxes to block mobile signals."
