EARTH STATION ANTENNA £¨Offset Feed£©
We
have developed the 1.8 meter C-band and Ku-band antennas to offer superior
performance for receive only and satellite communication transmit-receive
applications.
The
antennas meet the requirements for 2¡ãsatellite spacing per FCC
Docket 81-704 and INTELSAT specifications.
Options:
* Two port, three port, four port Rx/Tx linear circular polarized feeds.
Manual azimuth, elevation and
polarization drive systems.
