Pedestals/Positioners
Description: Typically two axes: the elevation axis (up/down) is mounted above the azimuth (side-to-side) rotation axis. It is commonly a post style. The payload mounts on the elevation yoke, offset from the azimuth axis, and is balanced about the elevation axis with adjustable counterweights or a combination of that and the customer's equipment.
An open/split yoke (antenna/sensor mounts in the center) style is available but typically more expensive. In this configuration, the payload is balanced about the elevation axis with adjustments to the customer load.
Model Series PG: Pedestal, Geared Drive
Pros: High output drive torque. Gearing provides motor torque multiplication factor at less expense than a direct drive.
Cons: Typically has gearing backlash, unless more expensive dual drive, zero backlash unit is specified.

Model Series PT: Pedestal, Torque-Motor (Direct Drive)
Pros: No gearing or backlash. Motor is directly coupled to the axis of rotation. Exceptional low- and high-velocity/-acceleration performance. Minimal moving parts for long life. Cons: More expensive than geared drive for the same output torque.
