The Sudbury transmitting station is a facility for telecommunications and broadcasting

transmission at Sudbury, England. It consists of two guyed masts, one, the original, being {{convert|165.8|m|ft|0}} high, and a second mast (no longer in service) at {{convert|103|m|ft|0}}. They have antennas attached at various heights. It is situated 14 miles WSW of Ipswich at a site height of 70m. All 6 Digital TV MUXES are transmitted from Sudbury using an omnidirectional pattern at an ERP of 100 kW. Originally Sudbury was a B group transmitter but in order to accommodate the digital transmissions it went E group then, at its 700MHz clearance in August 2018, it ended up a K group (or wideband). However, most B group, E group and wideband aerials will continue to work fine on it (see [https://www.aerialsandtv.com/knowledge/transmitters/sudbury-transmitter#sudbury-graph graph]).

It broadcast television and radio services to central and southern Suffolk and most of Essex, however southern areas of the county received a better TV signal from the Crystal Palace TV transmitter. This includes cities and towns such as Ipswich, Chelmsford, Colchester, Southend, Clacton-on-Sea and Haverhill. Signals can also be received as far as north Kent.

This transmitter has 8 local relays: Burnham-on-Crouch, Clacton, Felixstowe, Ipswich Stoke, Rouncefall (Ashingdon Essex), Somersham, Wivenhoe Park, and Woodbridge. {{cite web|url=https://ukfree.tv/maps/tvregions/45|title=Sudbury (including relays)|date=1 May 2004|website=UK Free TV|accessdate=11 September 2024}}
