Earth Station Antenna 11M

 

Antesky 11-Metr earth station antenna, which uses highly effective corrugated horn feed, provides high gain and exceptional pattern characteristics as well as low VSWR. The antenna system can fully meet the specifications associated with the international standards. 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.
