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.
