It was constructed in 1961 by the IBA to transmit ITV 405-line television with transmissions commencing on Band III channel 9 from antennas at 450 m (1,475 ft) above sea level.

Colour television came to the site in 1971.[1] Channel Four started up in November 1982. Stockland Hill never radiated the analogue Channel Five service.

Digital television was first introduced at this site in 1998, and Digital Switchover happened in May 2009. Stockland Hill was the second transmitter in the south west of England to have its analogue television transmissions shut off. BBC Two was switched off on 6 May 2009 and the rest of the analogue services were switched off on 20 May 2009 around after midnight.

Stockland Hill currently transmits all of the DTT multiplexes at full planned ERP. The three PSB multiplexes are at 50 kW, the other three multiplexes are at 25 kW.[2]
