LW/AW Mk Ⅰ
LW/AW (Light Weight /Air Warning) was operating in the VHF-Band air surveillance radar family used extensively by Royal Australian Air Force.
All versions were fitted with a 5 inch wide A-scope. The used antenna is a group of 16 dipoles in front of a common rectangle reflector area. The smaller antennas on top of the large reflector are used by the IFF Mark Ⅲ interrogator.
The version LW/AW Mark ⅠA was tropicalized. Version LW/AW Mark Ⅱ used the same antenna but a new one transmitter with a peak power of 40 to 50 kW. The maximum range increased to 130 nautical miles (≙ 240 km) then.
151 of these radars were built until the end of the 2nd World War.
