Earth Station Antenna 4.5M

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