The active field to the MDS comprises a circle (ANT D5) or a square (ANT D6, D10;
SLG D12/D12S). The MDS can be processed as soon as the crossover point (CP) of the
MDS enters the circle or square of the transmission window. The direction of movement and
rotation of the MDS has no effect.
From the diagrams above, it can also be seen that operation is possible within the area
between S
shrinks to a single point at distance S
between S
For more detailed information on the transmission windows of the individual antennas, refer
to the respective antenna or SLG chapters.
