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.

MVG light duty EL/AZ positioners provide accurate rotation, velocity, and direction with platform sizes up to 12.6 x 12.6 in (320 x 320 mm). Their rugged yet straight-forward construction ensures maximum reliability and trouble-free operation.

ULTRA UHC series polypropylene based broadband electromagnetic absorbers are the latest technology for RF test applications.

The polypropylene material has a highly uniform carbon density, throughout the material, which provides for more predictable results with no discontinuities.

It is the unique production technology which is the critical factor in achieving the highest electromagnetic reflectivity performance in an antenna measurement anechoic chamber or an emc chamber.

As an international EMC chamber supplier, we provide these polypropylene broadband absorbers for EMC test chambers worldwide.

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.

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.

These AZ/EL/AZ 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.

Their rugged and straightforward construction ensures maximum reliability and trouble-free operation.

This compact EMC Chamber with a 3 meter test range will settle into test areas of limited space while continuing to produce exceptional performance for EMC measurement. Emission test volumes of up to 1.5m are accommodated with very repeatable results. Suitable for EMC pre-compliance emissions and EMC compliance immunity testing.

MVG Series heavy duty AZ/EL positioners provide accurate rotation, velocity, and direction and offer turntable diameters up to 74 in (1880 mm). Rugged yet simple construction ensures maximum reliability and trouble-free operation.
