Installation
 Influence of Tag Angle (Reference)
The maximum communications distance can be obtained when the Antenna and Tag are installed in
parallel. When the Tag is installed on an angle, the communications distance is reduced. Consider the
effect of the Tag angle when installing the Tag. As reference data, the following diagram shows the rate
of reduction in communications distance according to the Tag angle. The horizontal axis indicates the
angle when the Tag surface and Antenna surface are in parallel at 0°. The vertical axis indicates the
relative communications distance when the angle is 0° at 100%, i.e., the rate in reduction of the com-
munications distance.
