The GD Satcom (formerly VertexRSI) C139M lightweight 1.39-meter mobile antenna is a compact design for
worldwide transmit and receive operation in Ka-band. This transportable antenna consists of a singlepiece carbon fiber composite reflector
mounted on a cable drive elevation-over-azimuth positioner. This results in a lowweight antenna with superior stiffness and high performance
under wind loading conditions.
The state-of-the-art design provides exceptionally low sidelobe and cross-polarization performance,
well within INTELSAT and EUTELSAT requirements.
The complete antenna system can be interfaced with most lightweight vehicle structures
for the purpose of mobile SNG applications.
