Modular Positioner
Document Actions
Features
- Modular (1, 2 or 3-axis) positioner for antennas up to 1.5m diameter
- Each controller module operates one axis on the positioner
- The positioner can cover ‘Whole Sky’
- Can be Peltier cooled for demanding environments
- Q-par Angus has supplied up to 6-axis positioners of this type used for multi-path elimination
The positioner is generally for indoor use or for use in a dry outdoor climate only, or can be supplied with a radome. If you require a fully weatherproof option, please see our range of All Weather Antenna Positioners.
Controller
An embedded controller unit is used for each axis. The controllers use the widely adopted MINT programming language, which is similar
to BASIC in its structure. The positioner axes are controlled via
a single RS232 connection. The positioner can be controlled most
simply by a computer terminal (not supplied) sending single commands.
Alternatively, we can provide a user-friendly GUI
application based on a Windows 95/98/NT/2000/XP environment
for more convenient control.

Note - The figures shown above are indicated for maximum continuous use, rather than absolute maximums. Positioner weight and dimensions are specified without counterbalance weights or antennas. Due to the modular nature of this positioner we may be able to accommodate more challenging specifications for such positioner designs; please contact us to discuss your particular requirements.
