A maximum communication range can be obtained by installing a tag so that the antenna surface and tag surface can be parallel to each
other. When you install the tag, take into consideration the influence of tag angle.
If the tag surface is not parallel to the antenna surface, the communication range deteriorates. The characteristic of communication
range deterioration depending on the tag angle is shown below.
