Pan-Tilt Antenna Positioner

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.

Computer-Controlled Positioning of Antennas


• Flexible payload mounting for all antenna types
• Solid and vibration-tolerant for vehicle-mounted applications
• Rigid worm gear design
(no belts/pulleys) provides steady images in windy environments

(no sag when powered off)
• Large payload capacity
(35 lb top; 70 lb side)
• Wide range of pan speeds
(< 0.0064º/sec to 50º/sec)
• Extremely precise positioning
(0.0064º with microstep)


• Alternate ranges of motion
• Heavy-duty side mount brackets
• Inertial Stabilization Module (ISM)


• Air and ground communications
• Shipboard communications
• Electronic surveillance
• Scientific and R&D
