Marine Antenna

Superior electrical performance. The antenna adopts carbon fiber material with light weight, high gain and low side lobe. Fast initial pointing.

Highlight

Ø Superior electrical performance.

Ø Auto tracking of polarization, the low frequency slip ring and high frequency joint are used to assure continuous rotation of azimuth of antenna.

Ø High automation, the work can be performed automatically by only selecting the tracked satellite without manual intervention.
