The Llanwrtyd Wells television relay station is sited on high ground by the hamlet of Cefn Gorwydd to the east of the village of Llanwrtyd Wells in Powys, mid Wales. It was originally built in the 1980s as a fill-in relay for UHF analogue television covering the communities of Llanwrtyd Wells, Cefn Gorwydd and the surrounding area. It consists of a 25 m (82 ft) self-supporting lattice steel mast standing on a hillside which is itself about 240 m (790 ft) above sea level. The transmissions are beamed broadly northwest and northeast to cover its targets. The Llanwrtyd Wells transmission station is owned and operated by Arqiva.
Llanwrtyd Wells transmitter re-radiates the signal received off-air from Llandrindod Wells which is itself an off-air relay of Carmel about 45 kilometres (28 mi) to the southwest. When it came, the digital switchover process for Llanwrtyd Wells duplicated the timing at Carmel with the first stage taking place on 26 August 2009 and with the second stage being completed on 23 September 2009. After the switchover process, analogue channels had ceased broadcasting permanently and the Freeview digital TV services were radiated at an ERP of 2 W each.[1]
