Dinnington, Ground Controlled Interception Station

Station 14G. Ground controlled interception radar was used for guiding night fighters onto attacking bombers. The earliest stations were "mobile" - they had equipment on wheeled caravans and temporary wooden hutting. "Intermediate" stations had aerial arrays mounted above and below a metal gantry, with separate operations huts. "Final" stations built from 1942 onwards had a brick operations block, known as "Happidromes", with a single rotating aerial array, with the equipment housed in a well underneath. The Dinnington GCI Station was in operation by April 1941.
