4.5m Antenna which uses a shaped parabolic reflector, provides high gain and exceptional pattern characteristics as well as low VSWR. The panels of 4.5m satellite dish 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. The reflector of 4.5 Meter Dish 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.
About the operation frequecncy,it has ku band 4.5m satellite dish,C band 4.5m dish antenna,4.5m X band antenna,4.5m S band antenna and ka band 4.5m dish antenna,4.5 Meter Dish.
Antesky 4.5m Antenna is available for a wide range of applications including wireless telecommunication service providers, Internet service provider, system operators and broadcasters throughout the world.
