6.2M Earth Station Antenna
Antesky 6.2-Meter Earth Station Antenna, which uses a
shaped parabolic reflector, provides high gain and exceptional pattern characteristics
as well as low VSWR. The panels of the main reflector are comprised of aluminum
sheets and ribs which are stretch-formed, and are riveted on the special mould,
so its electrical performance can fully meet the specifications associated with
the international standards.
Features
Optional Linear or Circular Polarization feed system;
C-band, Ku-band, Ka-band frequency as option;
2 port or 4 port available;
Fixed or motorizable pedestals;
Hot-dip Galvanized structural steel;
Guaranteed high-qualified antenna structure;
Self-aligning, Stretch-formed aluminum reflector panel;
Assembled and tested feed system before leaving factory;
Compact package design to cheap easily with low cost.
