Since 1956, Diamond Antenna has delivered precision microwave rotary couplers for use in radar and satellite communication antennas. Experience with the exacting tolerances necessary for microwave signal transfer is the basis for Diamond’s core competence in precision rotary component design and manufacture.

In 2001, Diamond-Roltran was formed to enter the next-generation slip ring business. Roll-Rings represent an extension of Diamond’s core competence in precision rotary components. This high performance technology enables unmatched rotary electrical transfer in those applications that require high power, low noise, and long life.
