Freeview services in the Larne area could be disrupted by the launch of new 4G mobile phone networks in the area, residents are being warned.
Mobile phone operators are rolling out new 4G networks, bringing mobile broadband to the borough.
But for some households, the new masts could disrupt Freeview, TV 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.
But at800, an independent organisation created to ensure that all UK viewers continue to receive Freeview, is advising that help is available for anyone affected.
With more 4G masts due to go live, any viewers who experience new disruption to Freeview should contact at800 on 0333 31 31 800 (included in mobile and landline call packages) 0808 13 13 800 (free from landlines, calls from mobiles vary in cost) or at via www.at800.tv
If a viewer lives in a house with its own aerial, does not have satellite or cable television and 4G at 800 MHz is diagnosed as causing disruption to Freeview, at800 will restore their television service to its previous quality.
If at800 believes disruption is due to 4G at 800 MHz, it will arrange for an accredited installer to check the cause and fit an approved filter to the TV system, at no cost to the viewer.
