Description
Starwin 7.3m antenna delivers exceptional high performance for
transmit/receive application in C ,Ku, ka, X band in Tx/Rx 2
ports, 4 ports or Rx 1 port with high gain ,low noise and low
microwave interference.
Starwin 7.3m 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.
