Model 1.5m Flyaway
C, X, Ku and Ka-Band Antenna
Flyaway Antennas
Description
The General Dynamics SATCOM Technologies lightweight 1.5meter flyaway antenna is designed for worldwide transmit
and receive operation in C, X, Ku and Ka-band. This portable
antenna consists of a carbon fiber composite reflector and
aluminum support structure. This results in a low-weight
antenna with superior stiffness and high performance under
wind loading conditions.
The unique shape and the accurate reflector surface
provide exceptionally low sidelobe and cross-polarization
performance, well within INTELSAT and EUTELSAT
requirements.
Repeatability is maintained with precision for the five
reflector segments and the feed support structure.
This design offers the light weight, durability and highaccuracy characteristics of carbon fiber composite reflectors
and the high-strength durability of aluminum alloy elevation
over azimuth mounts.
The 1.5-meter antenna system, including a Ku-band feed,
is packaged in two robust, portable cases. The reflector is
packaged in one hard case; two soft cases are available as an
option for the reflector.
