History

The station was built by the BBC in 1958 to provide a 405-line Band I (VHF) TV service for north west Wales, including the Lleyn peninsula, Anglesey and the north Wales coast. ITV's service was provided from the Arfon transmitting station, approximately 20 miles to the south on the mainland. 405-line TV was discontinued in the UK in 1985.

A few years later, the BBC's high power VHF (FM) radio services were added, including the Home Service, the Light Programme and the Third Programme.

In 1973 the site was chosen to become the area's main station for 625 line colour UHF TV. By this time, it was policy to co-site all UHF TV services at the same site, so Llanddona began broadcasting BBC One, BBC Two and ITV on UHF. S4C was added later in 1982 in time for its launch.

In the late 1990s, digital TV transmitters were added, carrying all six national multiplexes.

In 2006, digital radio transmitters were added for the BBC's national multiplex and also Digital One.

Llanddona was the site of the first TV, VHF radio, digital TV and digital radio broadcasts for the area.
