The Wenvoe transmitting station is a facility for broadcasting and telecommunications situated close to the village of Wenvoe in the Vale of Glamorgan, Wales, in the UK. It comprises a 248-metre (814 ft) guyed mast with antennas attached at various heights. The mast (with extension completed February 2008) plus the Main UHF antenna on top now gives a structure height of 260.7 metres (855 ft). The average height above sea level is 392 metres for the television antennas. It is owned and operated by Arqiva.
The original 230 m (750 ft) mast at the site was built in 1952 by the BBC to provide 405-line VHF television to south Wales and the west of England. The station broadcast on Band I channel 5 (66.75 MHz) from 15 August 1952 using its reserve transmitters, and from 20 December 1952 with its main high-power transmitters. It remained on air until the closure of 405-line television in 1985.
In 1955 VHF FM radio was added to the mast, carrying the BBC's Home Service. This was followed by the addition of the Light Programme in 1956 and the Third Programme in 1959.
In 1963 a second 191 m (625 ft) mast was built alongside the existing structure. This was in order to carry the new BBC Wales 405-line TV service on Band III VHF channel 13, and entered service on 9 February 1964. It too remained on air until the closure of 405-line television in 1985.
On 12 September 1965, a 625-line black and white television service BBC2 became available from Wenvoe on UHF. This new transmitter was capable of colour broadcasting from the start and was used for unannounced colour TV engineering test-transmissions from that point onwards.
