Ammanford transmitting station

The Ammanford transmitting station is a broadcasting and telecommunications facility located on Mynydd y Betws about 6 km to the south east of the town of Ammanford, in Carmarthenshire, Wales. The building was originally built by Messrs. T. Richard Jones of Ammanford for the BBC, entering service in 1968 acting as a relay transmitter for the now-defunct 405-line VHF television system.

The site has a self-standing 30 m lattice tower erected on land that is itself about 330 m above sea level. The television broadcast primarily covered the towns of Ammanford, Brynamman, Cwmamman and indeed much of the valley of the Amman river.

405-line television from this site was shut down in 1983. From this point onwards, the site has handled telecommunications services only (including service as a mobile phone mast).
