Description

Description
Alignsat 4.5m feed forward antenna can deliver superior performance for sat communication applications such as Broadcasters, Service Providers, GSM operator, Satellite operator, Military and Government  Agencies, FreeLands or Rescue Organizations.
Alignsat 4.5m feed forward antenna adopts all aluminum re-enforced reflectors, consisting of precisely formed panels with matched radials and hub assemblies ensure the ease of installation. The standard designed azimuth over elevation pedestal provides a cost-effective solution for high stiffness and stability, full orbital arc coverage and fine drive performance, and ensures the pointing accuracy for C-Band Rx and Ku-Band Rx operations.


Features
  • Feed forward antenna, single pole stand, drive mode: manual.
  • High gain, low side lobe, high cross-polarization isolation.
  • C/Ku band optional, linear/circular polarization optional.
  • Meets CCIR 580 and INTELSAT Requirements
