The Bronwydd Arms television relay station is sited on high ground to the west of the village of Bronwydd to the north of Carmarthen. It was originally built in mid 1989^[1] as a fill-in relay for UHF analogue colour television covering the village of Bronwydd Arms and the surrounding community. It consists of a 14 m wooden telegraph pole standing on a hillside which is itself about 85 m above sea level. The transmissions are beamed east to cover the target. The Bronwydd Arms transmission station is owned and operated by Arqiva.

Bronwydd Arms transmitter re-radiates the signal received off-air from Carmel about 30 km to the southeast. When it came, the digital switchover process for Bronwydd Arms 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.^[2]
