Overview
The PDA-120MIL is a compact and sophisticated design for Military Communications. Aerodynamic design of PDA-120MIL provides wind load resistance due to its highly durable zero backlash elevation over azimuth and polarisation motorised chassis.
PALS offers auto-acquisition satellite tracking with Beacon reciever. It's possible to operate with minimal training by "One Touch" feature. The extreme ease and acquisition speed will guarantee that you will not loose the connection, even in rugged environmental conditions.
The PDA-120MIL Drive-Away Antenna’s precision, accurate reflector surface and dual optic design provides remarkably low sidelobes and excellent cross-polar performance. It has a three axes positioner which provides full antenna rotation and entirely backlash-free drive system. High precision pointing via resolver, boosted with 16 bit chip sets.
