Antesky 13-Meter earth station antenna system of trussed type search and track the satellite singles among the regulated operational frequency in the random, provids high gain and exceptional pattern characteristics as well as low VSWR. The reflector is a composite structure in which the panels are stretch-formed and riveted with its rings and ribs with high accuracy and supported with backups so as to meet the designed surface accuracy. Antesky earth station antenna systems are available for a wide range of applications including wireless telecommunication service providers, internet service provider, system operators and broadcasters throughout the world. Antesky is a professional earth station antenna supplier.
Features:
1) The main reflector adopts shaped cassegrain antenna and designed by advanced CAD technology so that the antenna can get high effective, low noise temperature and low sidelobe.
2) Feed horn has the characteristics of highly effective corrugated horn, wide beamwidth and highly-purified Polarization.
3) High reliable and anti-hash environment ability;
4) The design is more humane, more convenient to operate.
5) Adopt AC speed motor drive control system, reliable and convenient to operate.
