Type 279 radar 
Summary
The Type 279 radar was a British naval early-warning radar developed during World War II from the Type 79[1] metric early-warning set. It initially had separate transmitting and receiving antennas that were later combined in the Type 279M to single-antenna operation. This set also had a secondary surface-search mode with surface and aerial gunnery capability and used a Precision Ranging Panel, which passed accurate radar ranges directly to the HACS table (analog computer).[2][3]
