MI-55000 Family of Azimuth over Elevation over
Azimuth Positioners
 Features
- Versatile configuration allows precise pointing of the upper
AZ/EL positioner
- Rugged construction assures superior reliability and longevity
Description
The MI-55000 Family of Azimuth over Elevation over Azimuth
Positioners is our most versatile family of positioners. The
lower azimuth axis on these positioners allows precise pointing
of the upper azimuth over elevation axes.
This configuration allows a range designer to configure
multiple-source ranges. With this range design, the test
positioner is located at the intersection point of the different
source antenna’s radiating path.
