Type 293 radar

The Type 293 radar was designed as a short-range aerial-search radar for surface ships in 1945. It used the same transmitter as the Type 277 surface-search radar, but used a new antenna design intended to cover the area above the ship to provide air warning instead of surface search. The stabilised "cheese" antenna, 6 ft diameter in the AUR antenna, was upgraded to 8 ft in Type 293P and to 12 ft in the postwar Type 293Q.
