Description
Alignsat 4.5m antenna delivers exceptional high performance for transmit/receive application in C ,Ku, and other Multi-band in Tx/Rx 2ports, 4 ports or Rx2 ports with high gain ,low noise and low microwave interference.
Alignsat 4.5m antenna offers a fine reflector design with a stretch formed double contoured panels, strong back struts and hub for ease of field alignment. The standard designed azimuth over elevation pedestal provides a cost-effective solution for ground or roof installation with high stiffness and stability, full orbital arc coverage and fine drive performance, and ensures the pointing and tracking accuracy.


Performance Strength
  • C,Ku, and Multi Band available, meeting or exceeding FCC and ITU-RS-580 requirements.
  • High quality aluminum reflector panels and galvanized steel backup structure.
  • Self-aligning aluminum antenna reflector-no field alignment.
  • Galvanized steel elevation over azimuth pedestal.
  • Field changeable feed system, switchable circular to linear C-band.
  • Fixed foundation and Non penetrating foundation optional for wider choice.
  • Survives 125 mph winds in any position and High wind configuration optional.
