The CPI Satcom & Antenna Technologies Inc. (CPI SAT) lightweight 1.8-meter mobile antenna is designed for quad-band transmit and receive operation worldwide. 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.
