RDF Radar Tower
Heritage Open Day: WWII Radio Direction Finding (RDF/Radar) Tower Built in 1941, the RDF tower houses a very rare survivor from WWII, a type 287 aerial array. This is probably the only type 287 still in its original position. The tower monitored the minefield installed between Beacon Hill and Landguard Point and would have detected German Navy vessels as they entered the estuary. The RDF system had a range of 2.2 miles (3500 meters), enough to cover the entire minefield.
