Dunnet Head Radar Station was a World War II radar station located on the peninsula of Dunnet Head, Caithness, on the extreme north coast of Scotland. The site lies adjacent to Easter Head, the most northerly point of mainland Great Britain (which is not the more popularly quoted John o'Groats).
Burifa Hill Gee Station was located in the top of the hill of the same name, less than one mile to the south.
Dunnet Head was the site of Admiralty Experimental Station No 6, the last of a series of six centimetric early warning (CEW) stations commissioned to defend the Fair Isle Channel against U-Boats. The stations were designated as Coastal Defence U-Boat (CDU), and were tasked with detecting both surface vessels and low flying aircraft out to a range of approximately 100 miles.
