4.5M Earth Station Antenna

4.5m C/KU band Earth Station antenna, which uses a shaped parabolic reflector, provides high gain and exceptional pattern characteristics as well as low VSWR. Its reflector is supported by galvanized steel fixed ormotorizable pedestal that provides the required stiffness for pointing and tracking accuracy, and it can be installed on the ground or rooftop. The panels of 4.5m C/KU band VSAT antenna are made of stretch-formed aluminum sheet and riveted on the precise mould; such structure has the characteristics of higher accuracy and strong rigidity. 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.
