Twins of the Dwingeloo Radio Telescope

Some of you may recognize the telescope above as having the same design as the Dwingeloo Radio Telescope (DT). This is correct; the design of the DT was exported to the UK, where Dr Hey, of the Royal Radar Establishment, built an interferometer based on two Dwingeloo Telescopes. Unlike the original, the telescopes in Defford (close to Malvern) are placed on rails to form a baseline with length up to 1 km, either East-West or North-South.

One of the telescopes is still there. It has been fitted with a tripod, and currently is part of E-MERLIN.

The image above was part of an exposition of the Malvern Radar and Technology History Society (MRATHS) in 2016.
