Mutual Interference with RF Tags (Reference)
To prevent malfunctioning due to mutual interference when using more than one RF Tag, leave suffi-
cient space between them as shown in the following diagram.
Influence of RF Tag Angle (Reference)
Install Antennas and RF Tags as parallel to each other as possible. Communications are possible even
when an Antenna and a RF Tag are mounted at an angle, but the communications distance will be
shortened. The relation between the angle and the communications distance is shown below.
