Permissible directions of motion of the MDS

Coverage area of antenna and direction of motion of MDS
The MDS and antenna have no polarization axis, i.e. the MDS can come in from any
direction, be placed at any position, and cross the transmission window. The data of the
transmission window do not differ. The figure below shows the coverage area of the antenna
for various directions of MDS motion:
Transmission window
Direction of motion of the MDS
Coverage area L x W
