Every Decibel Preserved. Every Rotation Controlled.

Ground-based tracking antennas track satellites nonstop as they move at nearly 28,000 km/h. They send and receive high-frequency RF signals through rotating joints. At microwave frequencies, even small impedance mismatches or insertion losses matter. They can greatly reduce link quality and antenna efficiency. These systems must hold precise electrical properties across wide frequency bands. They must also handle high power levels. Any break in the signal hurts tracking accuracy and link uptime. FlowTurn's RF Rotary Joints keep insertion loss low, VSWR stable and isolation high while they turn. For higher frequencies, Waveguide Rotary Joints are also available. The result is reliable links for SATCOM earth stations, ATC radar, deep-space antennas and weather radar.
