MAC motors control antenna by JVL
2 MAC800 motors position a parabolic antenna for Dutch TV

For TV transmission of moving events, such as cycle racing (Tour de France, etc.) the most common method of transmitting the signals from cameras to the stationary control room is by sending the signals from a helicopter or small plane.
An antenna mounted on the stationary control room must thus follow the aircraft in order to prevent loss of signal due to the aircraft’s movement. Until recently this was done manually, by a person who constantly adjusted the antenna according to the aircraft’s position.
A Dutch TV company has now developed a tracking control system for the antenna, using 2 MAC800 motors and 2 Spinea backlash-free gears that adjust the antenna position depending on signal strength. JVL MAC motors were selected for the application due to their built-in circuitry (which results in very few cables to the motor) and the facility for communication directly via RS485. This made it very easy to synchronise control of the motors with the PC that processes changes in antenna signal strength.
Furthermore, JVL’s user-friendly MacTalk software made it very easy to adjust the motors to ambient conditions such as wind velocity, etc.
