2.4 M SATCOM OTP Antenna System

Cleared by US DoD/OSR for Public Release under OSR case number 10-S-1212 dated 06.11.2010.
2.4 METER VEHICLE/TRAILER-MOUNT SATCOM ON-THE-PAUSE ANTENNA SYSTEM
The DRS 2.4 Meter Vehicle/Trailer-Mount SATCOM On-the-Pause
Antenna System offers the most robust and light-weight antenna
of its type and size available. This antenna features a carbon
fiber composite reflector and backbeam structure designed to
provide exceptional performance in a lightweight package. The
custom-designed elevation-over-azimuth cable drive pedestal
provides superior stiffness over existing products on the market.
In addition, the antenna is designed to meet international
performance specifications for commercial or military
applications and is readily available in C, X, Ku and/or Ka-Band
frequencies. Multiple feed configurations are available.
Paired with the DRS FAC-50 Embedded Flexible Antenna
Controller (FAC) and servo motor drive solution, there is no need
for expensive and heavy cable runs to traditional rack-mount
antenna controllers. The FAC-50 is directly mounted on the
antenna platform and an Ethernet interface allows the user to
monitor and control the antenna from anywhere on the local or
wide area network.
The Windows®user interface comes complete with easy-to-use
satellite databases and North American Aerospace Defense
Command (NORAD) Two-Line Element (TLE) update tools for
program track functions.
