The EH118 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.

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.

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.

An EMC Chamber with 5 meter test range ensuring EMC compliance testing for Emission and Immunity testing. Ferrite and hybrid pyramidal absorbers are combined in a unique pattern within a SmartShield high performance chamber. Operating at a 5m test distance, this EMC chamber is compliant to CISPR-16-1-4 / ANSI C63.4 with a measurement zone diameter of 2 to 4 meters.

MVG medium duty azimuth positioners provide accurate rotation, velocity, and direction and offer turntable diameters up to 30 in (686 mm). Rugged yet simple construction ensures maximum reliability and trouble-free operation.

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.
