Influence of Metal behind Antenna (Reference)

If the Antenna is mounted to a metal object, the communications area will be reduced by approximately
10% compared with mounting to a non-metal object. Consider this influence on performance when
mounting the Antenna.

Mutual Interference between Antennas (Reference)

When installing multiple Read/Write Antennas adjacently, make sure that the Antenna communications
area do not overlap.
For details on the Antenna communications area, refer to Communications Area (Reference).
As a guide, the following diagrams show the minimum distances required between two Antennas
installed facing each other or in parallel. Be sure to provide the distance between Antennas shown
here.
• Installing the Antennas Facing Each Other
1 m min.
• Installing the Antennas in Parallel
50 cm min.
