The Caradon Hill transmitting station is a broadcasting and telecommunications facility on Bodmin Moor in the civil parish of Linkinhorne, located on Caradon Hill, Cornwall, United Kingdom. It is 6 km north of Liskeard, and 1.25 km south-east of Minions, the highest village in Cornwall (grid reference ). Built in 1961, the station includes a 237.7 metres (780 ft) guyed steel lattice mast. The mean height for the television antennas is 603 metres (1,978 ft) above sea level. The site has two smaller towers used for telecommunications and a wireless internet signal. It is owned and operated by Arqiva.
The South Caradon Copper Mine, 1 km to the SW of the transmitter, was the largest copper mine in the UK in its heyday, 150 years ago. Many other copper, tin and granite mines are scattered around the base of the hill.
The station was built in 1961 by the Independent Television Authority to bring ITV to South West England for the first time. Inaugural broadcasts were from the ITV franchise holder for the area, Westward Television. 405-line monochrome transmissions were on channel 12, Band III VHF. The station was also the first in the area to broadcast television using Band III.
In 1969 it was chosen to become a main station in the new colour UHF television network, broadcasting BBC One, BBC Two and Westward Television. Both the UHF and VHF services continued in tandem until 1985, when VHF television was discontinued in the UK.
Digital switchover began at Caradon Hill in the early hours of 12 August 2009. At approximately 1.15am the analogue BBC Two signal was switched off. The other analogue signals (BBC One, ITV and Channel 4) along with digital Multiplex 1 were then temporarily switched off in sequence. Between one and two hours later the analogue BBC One, ITV and Channel 4 signals were restored in sequence along with Multiplex 1 which was moved from UHF 34 to UHF 28 – analogue BBC Two's frequency.
The rest of the analogue signals were switched off permanently just after midnight on 9 September 2009. Once the digital signals were reshuffled to take advantage of the space left by the switched off analogue signals, they were then brought up to full power (digital signals were broadcast at a much lower power pre-switchover). This completes Caradon Hill's switchover to digital. This also completes the West Country region's digital switchover.
