RAF Stenigot was opened in 1940 as an east coast Chain Home radar station. Stenigot provided long range early warning for raids from Luftflotte V and the northern elements of Luftflotte II along the approaches to Sheffield and Nottingham and the central midlands.

East coast stations were built to the same design as the experimental radar establishment set up at Bawdsey in 1936 consisting of a protected transmitter and receiver block with transmitter aerials suspended from four 350' steel towers and the receiver aerials mounted on four 240' timber towers. The operations blocks of an east coast CH are classified as Type A with a 5' 6" layer of shingle on the roof to disperse blast, and earth banks around them.
RAF Stenigot was also provided with a buried reserve which consisted
of duplicate transmitter and receiver blocks at a dispersed location.
The stand-by set house, which at Stenigot has now been demolished, was
of similar construction.
After the war, the station remained operational as part of the 'defended area', a line of chain home stations running down the east coast from Flamborough Head in Yorkshire and along the south coast to Portland Bill in Dorset.
The existing equipment was modified and renovated to provide temporary cover during the construction of the new protected radar sites.
Following the full implementation of ROTOR Stenigot was taken off line and placed in care and maintenance.

In 1959, Stenigot was selected as part of NATO's Ace High communications programme developed in the mid 1950's.
Ace High was a tropospheric scatter/microwave link system providing an exclusive communications network comprising 49 tropospheric scatter links and 40 line-of-sight microwave links. It extended from northern Norway and through central Europe to eastern Turkey and included 570 voice, 260 telegraph and 60 data circuits at 84 sites.
The Ace High station
utilized 4.72 acres of the former CH site between the earlier transmitter
and receiver blocks. It was enclosed within a security fence and provided
with high intensity lighting. A two storey police house stood at the
entrance gate part way along a track running north west from the road.
The most prominent feature was two pairs of parabolic dish antenna,
60 feet in diameter supported on seven lattice steel girder legs.
