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.
Features of 7.3M Earth Station Antenna
Optional C-band, ku-band, ka-band frequency; Linear or Circular Polarized feed system as option; 2 port or 4 port available as option for 7.3m vsat antenna Fixed or motorizable pedestals for 7.3m vsat antenna Self-aligning, Stretch-formed aluminum reflector panel for 7.3m vsat antenna Guaranteed high-qualified antenna structure Assembled and tested feed system before leaving factory; Hot-dip Galvanized structural steel for 7.3m vsat antenna Compact packaging design for ease and low-cost shipping.
