CPI SAT C140M Vehicle Mount Ku Ka-Band Mobile Antenna
Ka-Band or Ku-Band, ideal for smaller vehicles
C140M Ka-Ku
The CPI SAT (formerly GD Satcom Technologies & Prodelin) lightweight C140M 1.40-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.
The complete mobile vehicle VSAT antenna system can be interfaced with most lightweight vehicle structures for the purpose of mobile SNG applications.
