Raytech’s ANTS-KA20CDW0 antenna assembly operates at 17 - 21 and 27 – 31 GHz with 20 dBi gain for K/Ka-band SATCOM. Features constant beamwidth for reflector feeds, supports circular polarization, and delivers low sidelobe levels


Antenna Assembly, 17 - 31 GHz, SATCOM, Dual Circular Polarization

 

Part Number: ANTS-KA20CDW0

The Raytech ANTS-KA20CDW0 antenna assembly is engineered for K/Ka-band SATCOM applications, covering 17–21 GHz and 27–31 GHz with 20 dBi gain. Designed for constant beamwidth, it is ideal for reflector feed systems and supports dual circular polarization through an integrated orthomode transducer (OMT). A built-in high- and low-pass filter provides 80 dB isolation between uplink and downlink, ensuring exceptional signal purity and interference-free operation.
