Computer-Controlled Positioning of Antennas

The PTU-D300-RF provides fast, accurate positioning of antennas and other payloads. It features a DC-18Ghz RF rotary joint and slip-ring to provide continuous pan rotation including pass-through for DC-18 GHz RF, power, and serial/ control lines. Real-time control capabilities make the D300-RF ideal for tracking applications. The durability of the D300-RF makes it ideal for demanding harsh, all-weather environments such as air, ground, or sea vehicles and for applications that require high duty-cycles.
