The CPI SAT (formerly GD Satcom Technologies & Prodelin) lightweight C139M 1.39-meter mobile Ka-Band antenna is a compact design for worldwide transmit and receive operation in Ku-band. 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. 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.
