13m EARTH STATION
ANTENNA £¨Ring Focus£©
We
have developed the 13 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.
¡ùMotorization
azimuth, elevation and polarization drive systems
