Installation
 Influence of Angle (Reference)
Install Antennas and Tags as close to parallel to each other as possible. Communications are possible
even when an Antenna and a 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.
