Effect of Surrounding Metals on the Antenna (Reference)
Instead of mounting the Antenna on the surface, it can be embedded into the metal work to prevent
collision with the workpiece and/or equipment.
If the Antenna is too close to metal, the communications capabilities may be significantly affected.
Make sure that the following minimum distances are maintained when mounting the Antenna this way.
Do not bend the cable into a curve tighter than 12 mm in radius.
The communications range will be reduced significantly if the Antenna is installed closer than 30 mm to metal surfaces.
Mutual Interference between Antennas (Reference)
To prevent malfunctioning due to mutual interference when using more than one Antenna, leave
sufficient space between them as shown in the following diagrams.
