RF Rotary Joints and Integrated Rotating Subsystems
Diamond Antenna rotary joints are electro-mechanical devices used to transmit radio frequency (RF) signals through a rotational interface via waveguide or coaxial lines. Ancillary items can be incorporated to pass system power, data signals, fiber connections, air and/or fluid to form a complex integrated rotational subsystem. Diamond supplies these items for a wide variety of applications including: military and commercial Satcom and Radar for ground, shipboard, and airborne systems. Specialized designs are available for Air Traffic Control and Weather Radar, Space Platforms, and Medical applications. Additionally, Diamond will overhaul and repair aged products to like-new condition regardless of the original manufacturer.
