Full description
This building housed the Commutated Antenna Direction Finder, which was replaced by Digital Resolution Direction Finding in the 1980s.
A. Cattermole (HES), 17 June 2013.
According to (S1) the building is windowless with a single access point. It has a 6 inch concrete slab roof and is constructed above a slightly raised concrete raft. It is surrounded by twelve 8 inch-square reinforced concrete columns that are taller than the building and arranged in a circle. There is a similar ring of six posts above the roof. These were used to support a horizontal counterpoise aerial array but this is now missing.
Three timber poles of unknown function (Building 136) arranged in a triangle to the south of this building may have been connected with monitoring and calibration of the system.
