MVG Performance Series heavy duty AZ/EL/AZ positioners represent the latest generation of multi-axis rotary positioning subsystems with turntable diameters up to 70.9 in (1,800 mm). They offer enhanced capabilities and improved performance relative to size and incorporate new engineering advances.

The Performance Series EL/AZ positioners represent the latest generation of multi-axis rotary positioning subsystems. They offer enhanced capabilities and improved performance relative to size, and incorporate new engineering advances.

These positioners provide accurate, balanced rotation, and controllable velocity. Their rugged yet straight-forward construction ensures maximum reliability and trouble-free operation, yielding the best size and weight/performance ratio. Typically, the unit includes the body, precise slew bearings, DC motor, gear reducer, encoder/synchro, and limit switch assemblies. The AUT mounting surface is designed with a threaded mounting hole pattern for ease of use. A Safe/Operate switch is included to ensure safety.

The MVG-Orbit/FR performance series has recently been expanded to include the AL-428X series of medium-duty, two axes positioners. Thanks to their low profile design and advanced drive mechanism, these symmetrical EL/AZ positioners ensure accurate, balanced rotation, and controllable velocity. 

Their rugged and straightforward construction ensures maximum reliability and trouble-free operation, yielding the best size and weight / performance ratio. This series includes a counter weight option which improves overall system stability and accuracy while allowing for higher DUT loads.

Typically, the unit includes the main body, precise slew bearings, DC motors, gear reducers, encoder and limit switch assemblies. The antenna interface mounting plate surface is designed with a threaded mounting hole pattern for ease of use. A large variety of options is available for this ORBIT/FR standard product family. See the Options pages in the Positioners Overview or on the website for slip rings, rotary joints, high precision encoders, speed options and more.

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.

The Virtual EL/AZ/Roll Positioner represents the latest generation of multi-axis rotary positioning medium-duty subsystems. It offers enhanced capabilities and improved performance relative to size and incorporates new engineering advances.

Particularly suited for testing direction-finding antennas, the virtual elevation axis enables rotation of the DUT around its phase center, placing the mechanical support system behind the DUT. This feature maintains the center of the DUT in one place, while eliminating scattering and interference from the positioning structure.

The MVG-Orbit/FR Legacy Series Polarization Positioners provide accurate, balanced rotation, and controllable velocity for the positioning of very large devices in test configurations. Their rugged yet straight-forward construction ensures maximum reliability and trouble-free operation, yielding the best size and weight/performance ratio.

MVG light duty polarization positioners provide accurate rotation, velocity, and direction and offer turntable diameters up to 12.6 in (320 mm) . Their rugged yet simple construction ensures maximum reliability and trouble-free operations.

Pylons are stationary metal Device Under Test support structures designed to minimize measurement signal backscattering.

Their shapes, sizes, and construction specifications are determined by requirements such as maximum DUT size, its mechanical properties, and minimum rotator size.
