RDR-50X is a short to medium-range precipitation radar operating in the X-Band for local severe weather warnings.

The antenna is 6 feet (≙2 m) in diameter and uses only linear horizontal polarization. The transmitter uses a magnetron.

Despite its low price, the radar failed to gain market acceptance.
