The maximum communication range can be achieved when the antenna face and tag face are in parallel with each other. If the
antenna and/or tag are inclined, the communication range becomes small. Install the tag paying attention to the tag angle.
•
For the tag rotating angle 0 degrees and 90 degrees, deterioration characteristic of communication range depending on the tag angle
is shown below.
•
Because of antenna position in the tag, communication range deterioration varies depending on the installation angle (whether "+" or
"-").
