Description
Starwin 4.5m compact C&KU Rx only antenna delivers exceptional high performance for receive application in
C &Ku in Rx 2ports, or 4 ports with high gain ,low noise and low microwave interference.
Starwin 4.5m compact C&KU Rx onlyantenna 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.
