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.

Bronwydd Arms transmitter re-radiates the signal received off-air from Carmel about 30 km to the southeast.

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] Bronwydd Arms entered service on the same day as did the nearby repeater at Cynwyl Elfed.

The UK's digital switchover commenced at Carmel (and therefore at Bronwydd Arms and all its other relays) on 26 August 2009.
