AL-48000 model towers are suited for medium duty applications with an operating load of up to 1,000 lbs (455 kg). This series is available with either a manual hand-wheel or motorized linear offset slide. The mast (vertical or inclined) is available in fiberglass or aluminum construction.

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.

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 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.

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.

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-9504-2 Emergency Stop (E-Stop) Unit provides a central connection point for external emergency stop panic buttons and positioner controllers that are located throughout the system. In the event of an emergency stop, the AL-9504-2 will command the appropriate positioner controller to disconnect motor drive power on all axes.

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.
