MVG - 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.

More Product Information
MVG heavy duty azimuth positioners provide accurate rotation, velocity, and direction, with turntable diameters up to 122 in. (3100 mm). Their rugged yet straight-forward construction ensures maximum reliability and trouble-free operation.
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.
The new MVG-Orbit/FR compact, low profile light duty positioners provide accurate, balanced rotation, and controllable velocity in the positioning of light duty antennas under test. Their compact and low-profile design optimizes space in test configurations as well as high operational performance, yielding the best size and weight/performance ratio.
The EH1840 EMC horn combines stable gain performance and low VSWR with wide band frequency operation. The horn is single linearly polarized with excellent cross-polar discrimination. The unique horn design suppresses any possible excitation of higher order modes in the aperture and maintains a well-defined smooth radiation pattern in the direction of the boresight axis throughout the operational bandwidth.
AL-58000 model towers are suited for very heavy duty applications with an operating load of up to 17,600 lbs (8,000 kg). They have durable steel masts, which can be vertical or inclined (limited to specific loads). They are available with a steel linear offset slide that is manual hand-wheel style, manual fixed step, or motorized.
The Null Seeker Positioner is used in development and production testing to emulate flight movement of a device encasing null-seeker sensors. Its high motion dynamics and ultra-precise angular positioning, rates, and acceleration allow for accurate evaluations of null seeker technology (ie. RF signal nulls transmitted from directive antennas).
