4.5m antenna Description


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. Our 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.
