About
The Ground Antenna System L/S/C/X/Ku/Ka -bands AFS-12 is a receiving two-mirror antenna system constructed according to the Cassegrain design. It is specifically engineered for use as part of satellite communications earth stations, facilitating the reception of satellite signals across a wide range of frequency bands: L, S, C, X, Ku, and Ka. The system features a 12.0 m reflector, along with replaceable irradiators and a counter-reflector. It also includes a slewing ring equipped with electromechanical drives for precise positioning. The AFS-12 supports remote polarization switching and offers replaceable irradiators for C-band, Ku/Ka-bands, and L/S/X-bands. It’s important to note that the structure does not incorporate radio receivers or radio transmitting devices. The product was released in 2017 and has a guaranteed service life of 15 years. It can be adapted to meet specific customer requirements, with an estimated production/delivery time of 18 months.
