Mobile broadband masts are set to ‘go live’ around Mansfield, and people are being warned that it could cause TV interference for those watching Freeview channels.
Signals from the new masts, which are to provide 4G services, may disrupt those watching the channels that are received through an aerial.
This is because some 4G signals operate at 800 MHz, adjacent to the frequencies used by Freeview.
TVs and set-top boxes that receive Freeview can fail to block the 4G signals causing interference such as a loss of sound, blocky images or loss of some or all channels.
More than 800 postcards have been delivered through doors to residents who may suffer such problems.
However, help is at hand for those who endure problems, courtesy of at800 - an independent organisation which was set up, and is funded, by the leading UK mobile operators.
Its role is to make sure that viewers can still watch Freeview, or are offered a suitable alternative. The service is free.
Ben Roome, CEO of at800 said: “New 4G mobile masts are bringing mobile broadband to Mansfield, but they do have the potential to disrupt TV reception for some households. We’re already helping viewers in the area and continue to offer support.
“We want to ensure that people know it’s our role to fix any disruption to Freeview due to 4G at 800 MHz and that there’s no charge for our support.”
Viewers who experience new disruption to Freeview should contact at800 on 0333 31 31 800 (included in mobile and landline call packages) or 0808 13 13 800 (free from landlines, calls from mobiles vary in cost).
