1.8m Motorized Flyaway Antenna System Manufacturer

1. Overview of 1.8m Motorized Flyaway Antenna System

ACF-180C/ACF-180INSATC/ACF-180K 1.8m auto-pointing portable flyaway antenna system from Antesky, with Gregorian dual-reflector offset feed, is mainly composed of turntable pedestal, support legs, back structure, support arm and motorized push rod etc. Antenna control subsystem includes azimuth, elevation, polarization motor. Antenna tracking subsystem contains beacon receiver, angle sensor, GPS, WiFi module, ATPC control board.

Antenna panel is made of composite carbon fiber material with light weight and high surface accuracy of 0.3 RMS. The Gregory double offset reflector design is updated with excellent electrical performance of low side lobe and remarkable cross-polarization. This flyaway antenna features 8 petals of carbon fiber panels, which can be assembled repeatedly with high precision.Two persons can assemble and no tools required during installation.

It is suitable for for temporary or frequently changing installation sites, or in where no regular communication means on the ground including earthquake disaster relief, TV broadcasting, maritime affairs, exploration, meteorology and other emergency communication fields. It can meet the requirements of CCIR 580-6, ASIASAT and INTELSAT as well.
