Ibsley HF-DF blast wall.

3D Model

Ibsley HF-DF was built as part of Middle Wallop’s Fighter Command Sector Control. Fighter Command stations, which were created in the build up to the Battle of Britain, required a method of locating their squadrons. Using Radio Direction Finding to tune into transmissions proved to be an effective solution. Each Station’s Sector Control was equipped with three HF-DF (huff-duff) sites about 30 miles apart to triangulate the position of the aircraft. Ibsley HF-DF was built as part of Middle Wallop’s sector control. The site was passed to Ibsley Airfield when Ibsley became a fighter control station in Feb 1941.
