PTU-D300-RF Antenna positioner
Rugged, flexible, feature-rich

The PTU-D300-RF provides fast, accurate positioning of antennas and other payloads.

Featuring a DC-18Ghz RF rotary joint and slip-ring to allow continuous pan rotation, it provides high torque for payloads up to 31.7 kg while maintaining speed, precision, and a small form factor.

The real-time control capabilities make the D300-RF ideal for tracking applications. Designed for durability in harsh environment such as air, ground or sea vehicles, the D300-RF is suited for demanding applications that require high duty-cycles and long-life in harsh all-weather environments.

The controller is fully integrated. A single mil-style connector provides power and pan-tilt control, as well as payload signal management (optional). Integrated flex-circuitry absorbs tilt motion for all internal wiring to provide long life over high duty cycles.

The built-in command set offers both ASCII and binary formats. This command set supports real-time control at up to 60 commands/second with very low and predictable latencies. The rich command set provides fine-grained control of position (absolute and relative), velocity, acceleration and other unit functions. The optional Geo-Pointing Module also provides an Ethernet/IP interface for control of the pan-tilt units
