Performance

Reliable maximum range, with antenna at 100', is 100 miles on medium bombers at 1,000' altitude. Range accuracy is ± 100 yards. Azimuth accuracy, ± 3°. There is no elevation control, but elevation can be estimated roughly from positions of maximum, and minimum signal strength

Transportability:

Shipment includes spares, with tubes for 400 hours, and separate generator if ship's power is DC. Not air transportable.

Installation:

SK has 10 components weighing approximately 5000 lbs. Heaviest unit (2400 lbs.) is the antenna assembly. Antenna measures 15' x 16'9". Antenna should be 100 ft. or more above water.

Personnel:
