Mendlesham transmitting station

Other sites considered in February 1958 for an ITV television mast were Tacolneston and Snetterton. By June 1958, the site was chosen. The site was in the village of Wetheringsett-cum-Brockford, but Mendlesham was the name of the nearby airfield.

For the new ITV region, the GPO would provide a link from London to Norwich, via Ongar, Essex, Sibleys Green (Chickney, to Mendlesham, then on to the telecommunications tower at Stoke Holy Cross, and by cable from there to Norwich. Construction began in January 1959, with the mast being built from April 1959.Suffolk and Essex Free Press Wednesday 29 April 1959, page 19 By June 1959 it was 600 feet. Construction finished in mid-July 1959, taking ten weeks.Haverhill Echo Saturday 25 July 1959, page 6

On Monday 5 October 1959, tests at full power of 200kW took place, from 10am to 9pm from Monday to Saturday.Haverhill Echo Saturday 10 October 1959, page 5Suffolk and Essex Free Press Thursday 15 October 1959, page 20 This was also the same day that the BBC started broadcasting from Norwich.Bedfordshire Times Friday 9 October 1959, page 20 It came into service on 27 October of that year. It was at the time the highest television mast to be constructed in Europe and the first of six of the same height subsequently used at other Independent Television Authority stations. It was fabricated in Hereford from zinc-galvanised steel, and was erected by British Insulated Callender's Construction Co. (BICC), now known as Balfour Beatty.

When UHF television came to East Anglia, main transmitters were commissioned at Tacolneston, near Norwich and Sudbury, near Colchester. Mendlesham was not required in the UHF plan, so when 405 line television was discontinued in the UK in 1985, the mast ceased to be used for any broadcast transmissions for over a decade.

However, in 1997, the site was chosen to be a main transmitter for new regional commercial radio station Vibe FM (renamed Kiss 105-108 in 2006), on 106.4 MHz VHF FM at a power of 20 kW. Vibe FM launched November 1997. Later in December 2001, national digital radio multiplex Digital One also added its antennas to the mast. The BBC National DAB Multiplex was added on 13 July 2010.

VHF analogue television was transmitted from Mendlesham from its launch in 1959 until the nationwide shutdown of VHF signals in 1985.
