About
The Antenna Feeder Device 4 is a transceiver two-mirror antenna system built on the Cassegrain system, specifically designed for use as part of earth stations in satellite communications C-band. It includes an antenna with a 4.5m reflector, an irradiating system, a counter-reflector, and a slewing ring with electromechanical drives. The structure does not include radio receivers and radio transmitting devices. Released in 2012, it has a guaranteed service life of 15 years and an estimated production/delivery time of 9 months. The product can be adapted to customer requirements. It operates with linear polarization, receiving frequencies from 3.4-4.2 GHz and transmitting frequencies from 5.7-6.6 GHz, offering high gain for both receive (≥41.1 dB) and transmit (≥45.6 dB) operations, and a cross polarization interchange of ≥30 dB. Its working angles are ±270° in azimuth and 0° to 90° in elevation, with working speeds less than 1.0°/s.
