About
The Antenna System 4,1 meters Ka is a receiving two-mirror antenna system built on the Cassegrain principle. It is specifically designed to receive signals in the Ka-band from satellites located on the Geostationary Satellite Orbit (GSO). The system includes an antenna with a 4.1-meter reflector, an irradiating system, a counter-reflector, and a slewing ring equipped with electromechanical drives. A key feature is its remote polarization switching capability, allowing for selection between circular or linear polarization. The system does not include radio receivers or radio transmitting devices. It was released in 2016, 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.
