Note
Going below the distances
If the distances (a and h) are not observed, a reduction of the field data results. It is possible
to mount the MDS with metal screws (M5). This has no tangible impact on the range. It is
recommended that a test is performed in critical applications.
7.7.4 Mounting in metal
It is possible to mount the MDS D139 in metal. With large antennas, for example ANT D5,
this leads to a reduction of ranges.
a
= 100 mm

NOTICE
Cleaning the transponder
Do not clean the transponder with mechanical tools, sand-blasting or pressure hose. These
cleaning methods result in damage to the transponder.
