Hob Uid: 1477319
Location :
Suffolk
East Suffolk

Grid Ref : TM4780068300
Summary : The site of a Royal Air Force Chain Home Low radar station at Dunwich established by December 1939. It provided early warning for low-flying enemy aircraft approaching the central East Anglian coast. It formed part of the radar warning systems for the key RAF Fighter Command 11 Group during the Battle of Britain. Chain Home Low sites typically comprised two gantries carrying the transmitter and receiver aerial arrays, a transmitter and receiver hut, a standby set house for the reserve power, and a general purposes hut. Defence measures installed at radar stations included Light Anti-Aircraft gun emplacements, pillboxes, road blocks and air raid shelters. Aerial photography from 1973 shows that two building bases are visible at TM 478 683 and potentiall more could exist under the scrub. A rectilinear outline shows the original fenced limits of the site.
More information : A Chain Home Low Station located at Dunwich (TM 478 683), called site CHL28A. It was established by 07-DEC-1939. Chain Home Low (CHL) stations provided early warning of approaching low-flying enemy aircraft during the Second World War. CHL stations used technology originally used by the Army to plot shipping for coastal batteries. In 1940 the Royal Air Force established the series of Chain Home Low stations to supplement the existing Chain Home stations as they were capable of detecting lower-flying aircraft. CHL sites typically comprised two gantries carrying the transmitter and receiver aerial arrays, a transmitter and receiver hut, a standby set house for the reserve power, and a general purposes hut. Defence measures installed at radar stations included Light Anti-Aircraft gun emplacements, pillboxes, road blocks and air raid shelters. NGR for the site in 1943 is given as TM 471 683. (1)
