Introduction
The 18.5 earth station antenna is trussed type antenna of our company, which can search and track the satellite signals among the regulated operational frequency at random, and also provide high gain, low VSWR and exceptional pattern characteristics. The reflectors of this antenna are stretch-formed and riveted with its rings and ribs with high accuracy, and have back structures to support so that it can satisfy the designed surface precision. Our earth station antennas can be applied in wide ranges throughout the world, such as system operators, broadcasters, Internet service provider and wireless telecommunication service providers. Features
The operation is more convenient and design is more humane.
Linear or circular polarization feed system for your choice
Own harsh environment resistance and high reliability
Optional C-band, ku-band, ka-band frequency.
