Antenna  Assembly, 17 - 31 GHz, SATCOM, 4 Channels

Part Number: ANTS-KA20CQW0

The Raytech ANTS-KA20CQW0 antenna assembly is designed for K/Ka-band SATCOM applications, operating across 17–31 GHz with 20 dBi gain. Its constant beamwidth makes it an excellent choice for reflector feed systems, while supporting for both LHCP and RHCP in uplink and downlink. An integrated diplexer delivers 80 dB isolation between K- and Ka-band links, ensuring interference-free, high-performance communication. With low sidelobe levels, this antenna provides exceptional signal quality and reliability for demanding satellite communication systems.
