Flyaway satellite antenna work by satellite as small earth base for communication. Mostly adopts offset strcuture to reduce the shelding of feed wavebeam. This manpack satcom antenna is high gain, low sidelobe, small size and light weight which is convenient for emergengy condition application due to easy stow and transportation.
The main components of this portable satcom antenna includes reflector, feed and mount. Feed is heart of antenna which is R&D ownself with high performance. And the feed support is integraty technology which just need few bolts to connect and fixed on antenna. In that way, the portable multiband antenna will guarantee the antenna performance well. Antenna reflector is carbon fiber skin and aluminum cellure inside structure for easy shaped. Antenna mount is selected A-E type structure which including Az and EL mechanism. This antenna carbon fiber used over 85% for all components. The compass are still integrated on antenna mount.
Flyaway antenna is designed and simulated under 8 level wind load as operational wind to guarantee antenna can bear the max wind load and worst weather comdition.
6-Piece Carbon fiber folding Reflector.
Pre-Assembled Tripod Base Mount w/Pull Pins.
Ku and Ka Band Feed Systems Available.
Sturdy Boom Accommodates Outdoor Units.
Adjustable Feet for Uneven Surfaces.
Optional Lightweight Cases for Easy Transportation.
5 Minute Setup, No Tools Needed.
