Freeview viewers in Salisbury and the Isle of Wight will have to retune their set-top boxes and television on May 15 in preparation for 4G services in these two areas.
Technical changes are being carried out at some local transmitters in the region and will require devices to be retuned in 46,000 homes. The retune is necessary so that frequencies for the future introduction of 4G mobile services can be freed up.
Between now and the end of 2013, similar upgrades will be made in other areas of the UK to prepare for 4G.
Reaad Recombu Digital’s guide to the 4G Freeview FailTV services will be subject to disruption from midnight on 15 May as channels including BBC One, BBC Two, ITV3 and QVC services are moved to new frequencies, according to the Digital TV Group.
Work at the main Salisbury transmitter is expected to be completed by 6am and viewers can retune at any point after this. Services from the Ventnor, Winterborne Stickland and Brightstone relays may be off air or subject to breaks until mid-afternoon. Once services resume, anyone missing channels should retune their TV or digital box to get them back.
Viewers can check if they need to retune and the TV services predicted to be available at their address both now and in the future by using the coverage checker at digitaluk.co.uk.
