offering multichannel complex rotary joints for Ka, Ku & X-band satellite-on-the-move (SOTM) high-data-rate communication systems for military or commercial mobile platforms on land, sea or air. We provide both coaxial contacting rotary joints & contact free rotary joints in frequency ranges from DC to 40 GHz. We can incorporate coaxial or waveguide designs integrated with slip ring and encoders. Our dual channel units have excellent isolation between channels some with very compact outlines where space is critical. We also offer much larger multichannel units for S-band air traffic control radar and similar systems.
