AN/MSG-1

AN/MSG-1 was operating in S-Band tracking and fire control radar for 90 mm AA guns. The system consists of an AN/TPG-2 tracking radar and a T-18 computer.

The antenna was a parabolic reflector with a diameter of 67 inch (1,7 m). It used the conical scan with a rotating dipole. The transmitter used a fixed frequency magnetron of Type 2J32.

AN/MSG-1 was required in 1949 and was deleted in 1973. It was replaced by AN/TSQ-73.

Attention! There is a frequently copied error in the original documents: They claim the transmission wave length of 10 cm but a frequency of 10,000 mc. However, neither the antenna nor the magnetron used gives this information.
