Description |
The Patriot 1.8 meter flyaway
c-band antenna is designed for worldwide transmit and receive
operation. This lightweight portable antenna system consists
of a solid metal reflector and a tripod base mount. This
results in an antenna with superior rigidity and high performance
under wind loading conditions.
The unique shape and the
accurate reflector surface provide good sidelobe and
cross-polarization performance. Repeatability is maintained
with precision registration of the reflector segments and the feed
support structure.
The 1.8m flyaway antenna
system is a derivative of Patriot's Intelsat type-approved products and provides excellent
performance that meets all international specifications. The
complete system, including a single feed, is packaged in three
portable cases. |
