2.4 Meter C240FM Manual Flyaway Antenna

The General Dynamics SATCOM Technologies lightweight 2.4- meter flyaway antenna is designed for worldwide transmit and receive operation in C, X and Ku-band. This portable antenna consists of a carbon fiber composite reflector and aluminum support structures. This results in a low-weight antenna with superior stiffness and high performance under wind loading conditions.

 

Features

The unique shape and the accurate reflector surface provide exceptionally low sidelobe and cross-polarization performance well within INTELSAT and EUTELSAT requirements. Repeatability is maintained with precision registration of the nine reflector segments and the feed support structure. The complete antenna system, including a single feed, is packaged in nine robust portable cases.

  • Carbon fiber reflector
  • Lightweight, precision surface and high stiffness
  • Easy deployment
  • Two-person assembly, captive hardware, precision alignment
  • INTELSAT type approved, EUTELSAT compliant
  • High performance
  • Low sidelobes and high E.I.R.P. capability

Options
