4-3 Influence of Tag Angle
The maximum communications range between the Antenna and Tag will be available if the face
of the Antenna and the face of the Tag are parallel to each other. The communications range will
be reduced if the Tag is mounted at an angle. Take the angle of the Tag into consideration when
mounting.
For reference, the relationship between the Tag angle and the communications range is
illustrated in the graph below. The horizontal axis represents the angle between the face of the
Antenna and the Tag with 0° representing the state where the faces are parallel. The vertical
axis represents the relative communications range from when the angle is 0° and the
communications range is 100% (i.e., the percentage reduction in communications range).
