The Penderyn television relay station is sited on high ground to the east of the village of Penderyn in the Brecon Beacons. It was originally built in 1984 as a fill-in relay for UHF analogue television covering the communities of Penderyn and Hirwaun. It consists of a 12-metre (39 ft) self-supporting lattice steel mast standing on a hillside which is itself about 310 metres (1,020 ft) above sea level. The transmissions are beamed west and south to cover all these targets. The Penderyn transmission station is owned and operated by Arqiva. Penderyn transmitter re-radiates the signal received off-air from Carmel about 30 miles (50 km) to the west. When it came, the digital switchover process for Penderyn 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 2.6 W each.
