Type 268

Type 268 was operating in X-Band search, navigational and target-indication radar developed in Canada for the British Admiralty in 1944. It permitted detection of a battleship at 9 NM and a submarine snorkel at 3 NM. Since 1945 the radar was installed in coastal forces.

The antenna was of the “Cheese antenna” type, not stabilized against pitch and roll. The transmitter used a magnetron of type 725A.
