The Cwmgors television relay station is sited on high ground at Gwaun Cae Gurwen to the north of the village of Cwmgors in south Wales. It was originally built in 1983 as a fill-in relay for UHF analogue colour television covering the communities of Cwmgors, Gwaun Cae Gurwen and Tairgwaith. It consists of a 25 m self-supporting lattice steel mast standing on a hillside which is itself about 180 m above sea level. The transmissions are beamed broadly south to cover its targets. The Cwmgors transmission station is owned and operated by Arqiva.
Cwmgors transmitter re-radiates the signal received off-air from Carmel about 25 km to the west. When it came, the digital switchover process for Cwmgors 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 5.2 W each.
