Rotary couplings are electromechanical devices used to transmit radio frequency (RF) channel waveguide or coaxial signals with minimal signal distortion. These systems can also include accessory systems for connecting power circuits, fieldbus signals, fiber optics, gases and\/or fluids. Thus composing a complex rotary joint that combines multiple technologies. These elements are used for a wide variety of applications, including: Commercial and military Satcom and Radar and are suitable for both land, naval and airborne systems. Products specifically developed for air traffic control and weather radar, space platforms are available.<\/p>\n\n\n\n
