1.8 Meter C180FM Manual Flyaway Antenna

The General Dynamics SATCOM Technologies lightweight 1.8-meter SF antennas are designed for worldwide transmit and receive operation in C, X, Ku and Ka band. These portable antennas consist of composite reflectors and aluminum tripod base mounts. 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 good sidelobe and cross-polarization performance. Repeatability is maintained with precision registration of the nine-piece reflector segments and the feed support structure. The complete 1.8-meter antenna system, including a single feed, is packaged in multiple portable cases depending on options ordered.

  • Carbon fiber composite reflector
  • Tripod base mount
  • Less than 30-minute setup
  • Captive hardware/fasteners
  • No tools required
  • Quick adjust positioner
  • Intelsat/Eutelsat sidelobe compliant (C and Ku band)
  • Feed boom supports up to 40 lbs. for amplifier mounting
  • Lightweight transport cases

Options

  • Multiple feed configurations
  • Multiple colors
