Overview
The General Dynamics SATCOM Technologies lightweight 1.2-meter Quick Deploy antennas are designed for worldwide transmit and receive operation in C, X, Ku and Ka-band. These portable antennas consist of Precision Compression Molded reflectors and a compact aluminum pedestal. This results in a durable antenna with superior stiffness and high performance under wind loading conditions.
The unique shape and the accurate reflector surface provide good sidelobe and cross-polarization performance. The antenna system is a Series 1138 and the reflector consists of a two-segment SMC compression molded assembly. Repeatability is maintained with precision registration of the reflector segments and the feed support structure.
The 1.2-meter antenna, including the feed, is packaged in three portable cases.
