Description
Starwin 11m antenna delivers exceptional high performance for transmit/receive application in C ,Ku, ka, X band
in Tx/Rx 2 ports ,4 ports or Rx 2 ports with high gain ,low noise and low microwave interference.
Starwin 11m antenna offers a fine reflector design with a stretch formed double contoured panels, strong back
struts and hub fore 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 .
The electrical performance is compliant with FCC and ITU-RS-580 sidelobe specifications and Intelsat ,Eutelsat,
INMARSAT, ASIASAT,APT and CHINASAT, etc requirement.
