4.5m EARTH STATION ANTENNA £¨Ring Focus£©
We
have developed the 4.5 meter C-band and Ku-band antennas with superior
performance for receiving only and satellite communication
transmitting/receiving
applications.
The
antennas meet the requirements for 2¡ãsatellite spacing per FCC Docket 81-704 and INTELSAT
specifications.
Options:
¡ùTwo-port,
three-port, four-port Rx/Tx linear or and circular
polarized feeds.
¡ùManual or motorization azimuth, elevation and
polarization drive systems
With controls and readouts.
