Metal-free area

The antennas ANT1, ANT18 and ANT30 can be flush-mounted on metal. Please allow for a
possible reduction in the field data values. During installation, maintain the minimum
distances (a and b) on/flush with the metal.
NOTICE
Reduction of range if the metal-free space is not maintained
At values lower than a and b, the field data changes significantly, resulting in a reduction in
the limit distance and operating distance. Therefore, during installation, maintain the
minimum distances (a and b) on/flush with the metal.
