Description of 20M Large Satellite Dish Tx/Rx Antenna
Our 20M Large Satellite Dish Tx/Rx Antenna system of trussed type search and track the Satellite singles among the regulated operational frequency in the random, provides 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. This antenna system are available for a wide range of applications including wireless telecommunication service providers, Internet service provider, system operators and broadcasters all over the world.
