Introduction
Our 20m earth station antenna is trussed type antenna with high gain, low VSWR and exceptional pattern characteristics. It can search and track satellite signals within the regulated operational frequency randomly. Its reflector is with composite structure, in which the panels are stretch-formed and riveted with high accuracy, and supported with back structures to satisfy the designed surface precision. This kind of antenna also can be used in wide areas in the world, like Internet service provider, system operators, wireless telecommunication service providers and broadcasters. Features
Optional linear or circular Pol. feed system
C-band, Ku-band and Ka-band to choose
The shaped Cassegrain antenna main reflector is designed by advanced CAD technology so that it can get low sidelobe, low noise temperature and high effectiveness.
Adopt corrugated horn with high effectiveness, polarization with high purity and wide beamwidth.
High reliability and anti-harsh environment capacity.
2 port and 4 port are choosenable
Operating more conveniently and design with more humanization.
