Flyaway antenna pedestal structure

The flyaway antenna pedestal consists of azimuth adjusting device, elevation adjusting device and strut leg. The weight is 6.5kg. Before you know the flyaway antenna pedestal structure, maybe you’d like to know much more information about flyaway antenna, please visit Flyaway Antenna Introduction.

Each part of flyaway antenna pedestal can be demounted manually, loaded in bags, and removed and repaired by one person. When assembling flyaway antenna, take parts out from box and assemble manually. Three groups of pedestal support can choose reinforcement and wind-resistance measurement. Nail individually on three foot drives. Or press a sandbag on each strut to fasten fixed pedestal and adjust torsion bar to keep pedestal in horizontal level. For more information about the whole flyaway antenna structure, please visit An Introduction for Flyaway Antenna Structure.

Azimuth adjusting device mainly consists of azimuth turntable, star screw. When roughly adjusting, adjust triangle support. When fine adjusting, loosen star screw and drive azimuth turntable and then can adjust antenna’s azimuth angle (－30~30°). Lock star screw in the time of locking.

The mechanism is lead screw adjusting. One end is fastened on pedestal; the other end is connected with flyaway antenna reflector. When adjusting El, press knurl tightly and lock jacking block of screw to adjust in a wide range. And then loose jacking block, rotate knurl nut to adjust fine. The elevation range is between 15~50°when using lead screw. The El adjusting mechanism is shown in Fig3-46.
