Type 159

Type 159 was an early commercial navigation radar operating in the X-band.

Type 159 used a so called “Double Cheese Antenna” 4ft wide and an upmast transceiver. The display was a 9-inch cathode ray tube as PPI-scope. In 1950 it was the first commercial radar of DECCA.

Type 12

Type 12 used the same antenna, transmitter, and receiver but a 12-inch CRT and a reflection plotter. A version modified for military purposes was designated Type 974.
