Rotary Positioners

Performance Series - Virtual EL/AZ Positioners - Light Duty

This unique dual-axis positioner is particularly suited for testing direction-sensing antennas. The virtual elevation axis enables rotation of the DUT around its phase center, placing the mechanical support system invariably behind the DUT. This feature maintains the center of the DUT in one place, while eliminating scattering and interference from the positioning structure.
