Type 273Q
Type 273Q is operating in the S-Band naval surveillance radar. It was developed by the end of 1941 and in production in 1942. The radar used a strapped magnetron CV56 and rectangular waveguides. The reflector had a diameter of 4 ft 6". Type 173Q in a big ship (i.e. less rolling) gave 46.000 yards against a Battleship, 15.500 yards against a U-boat and 12 to 15 miles against low flying aircraft.
