Earth Station Antenna 7.3M

Antesky 7.3-Meter C/Ku-band Earth Station Antenna, which uses a shaped parabolic reflector, provides high gain and exceptional pattern characteristics as well as low VSWR. This antenna features advanced dual-reflector technology precision formed aluminum reflector assembly. The main reflector is self-aligning, eliminating the requirement for field alignmentso its electric performance can fully meet the specifications associated with the internatianal standards.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.
