About
The Antenna System 7.2 m L/S/X is a receiving two-mirror antenna system built on the Cassegrain design. It is specifically engineered for use as part of satellite communications earth stations to receive spacecraft signals across the L, S, and X-bands. The system includes a 7.2-meter reflector with an irradiating system and a counter-reflector, along with a slewing ring equipped with electromechanical drives. A key feature is its remote polarization switching capability, allowing for either circular or linear polarization. The system does not incorporate radio receivers or radio transmitting devices. It was released in 2016 and comes with a guaranteed service life of 10 years. The estimated production and delivery time is 12 months, and the product can be adapted to meet specific customer requirements.
