Support is being offered to residents in Renfrew for those who may suffer interference to their TV reception after new 4G mobile phone services were switched on in the area.

4G signals sit next to the frequencies used by Freeview (800 MHz) and there can be a small chance that some users may experience interference to Freeview, which is TV received via an aerial.

Signs of interference are loss of sound, pictures going blocky, freezing or the TV screen going blank or showing a ‘No Signal’ message.

Free help is available from a company called at800. Set-up under government direction, at800 offers support to households that rely on Freeview for their TV to resolve 4G related interference problems so that viewers in Renfrew can keep updated on current affairs and enjoy their favourite programmes.

at800 also offers extra support for people who are 75 years of age or older, are registered blind or partially sighted or receive any of the following benefits: personal independence payments (PIPs); attendance allowance; constant attendance allowance or War Pensioner’s Mobility Support.

Ben Roome, CEO of at800, said: “We want to ensure that people know it’s our role to fix Freeview interference caused by 4G at 800 MHz, and that there’s no charge for our service.

“If you rely on Freeview for TV, we can send you a filter to fit yourself, free of charge, which fits into the aerial lead connecting to TVs and set-top boxes to block mobile signals. Full instructions are included, and we can provide further advice online and by phone if needed.”

“In most instances, fitting the filter will resolve any interference from 4G at 800 MHz, but if this isn’t the case, we may also be able to arrange a follow-up visit from an at800 engineer at no cost, depending on eligibility.”

Cable and satellite TV, like Sky or Virgin, won’t be affected. However, if viewers have cable and satellite TV and also watch Freeview, at800 can provide free filters.

People who live in communal properties should contact at800 and also advise their landlords. at800 can provide free filters to landlords, but property managers are responsible for the cost of fitting these.

With more 4G masts due to go live, any viewers who experience new interference to Freeview should contact at800 on 0808 13 13 800 (free from landlines and mobiles) or visit www.at800.tv.
