Standing on the summit of North Hessary Tor in Devon, England is an FM radio and television transmitter which uses antennas on a 196 metres (643 ft) high guyed mast.

It was built by BICC for the BBC in 1955 when a transmitter was needed to introduce 405-line television into Devon, alongside Rowridge and Pontop Pike (both 500ft).

It now carries a small UHF TV transmitter which serves Princetown and Dartmoor.

FM radio transmissions began in 1956 and covers most of Devon and eastern parts of Cornwall, along with Somerset and South Wales as a backup for Wenvoe.

The mast covers a large area including Devon, Cornwall, Somerset and South Wales.
