The Stockland Hill transmitting station is a transmitting facility of FM Radio and UHF television located near Honiton, Devon, England.
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 1475feet 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 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]
This transmitter mainly serves the East of Devon, West Somerset and West Dorset. This includes cities and towns such as Exeter, Sidmouth, Tiverton, Exmouth, Taunton, Yeovil, Bridport, Weymouth and Sherborne.
405-line VHF ITV television arrived in the southwest with the simultaneous building of this station and Caradon Hill 60 miles (100 km) to the west in Cornwall.
UHF colour television commenced.

Digital switchover was completed at Stockland Hill. All analogue television was switched off and the new post-DSO multiplexes took over the analogue frequencies plus a few new ones. Full power could not immediately be achieved for the COM multiplexes due to interference issues at Rowridge and in France.[3] [4]
