The EH022 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.

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.

The AL-4188 series LCUs are portable, wireless hand-held units that are connected to a PCU/positioner controller via a wireless RF link. These LCUs utilize the PCU/ controller’s basic control, limit and supply circuits. They incorporate a rotary switch for axis selection, limit indicators, and a potentiometer for speed and direction control.

AL-4100 series PCUs provide precision motor drive for DC-servo based positioning and can control up to six axes sequentially. The AL-4107-6A models include a power supply unit (PSU) and a local control unit (LCU).

The AL-4164 and AL-4166 programmable controllers offer real-time control of positioning subsystems used in near-field and far-field antenna measurement systems. They may be configured to drive planar scanners and general purpose far-field positioners that are encoder-based or involve simultaneous motion.

The LCU AL-4189 - Local Control Unit is a hand-held control box specifically designed and built to be used in conjunction with ORBIT/FR controllers and PCU’s. It provides the attendant (operator, serviceman etc.) with a high degree of flexibility in operating the system elements.

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.
