7.3m C Ku Ka Band Erath Station
Product Details
Product Description
Staray 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.
Staray 7.3m antenna offers a fine reflector design with a stretch formed double contoured panels, strong back struts and hub for easy 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
