1.4 Meter C140M/MW High Wind Mobile Antenna

The General Dynamics SATCOM Technologies lightweight 1.40-meter mobile antenna is a compact design for worldwide transmit and receive operation up to Ka-band with tracking. This transportable antenna consists of a single-piece carbon fiber composite reflector mounted on a cable drive elevation over- azimuth positioner. This results in a low-weight antenna with superior stiffness and high performance under wind loading conditions.
