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 165.8 metres (544 ft) high, and a second mast (no longer in service) at 103 metres (338 ft). 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 graph).
