9.1 Installation location
The operating principle of the antenna is influenced by the type of installation and
the environment�
Observe the following remarks for the selection of the installation location:
●
Keep a distance of min� 70 cm to metal surfaces and the ground (see Figure 1)�
●
When installed in front of a metal surface, use a mounting bracket that
establishes a distance of exactly 12 cm between the back of the device and the
metal surface (see Figure 2)�
●
With direct installation on a metal surface (e�g� a plate as part of
a mounting bracket) use a square-shaped metal plate with the dimensions
16 x 16 cm (see Figure 3)�
●
Avoid conductive objects such as tanks with liquids in the vicinity of the
installation location� The objects influence the performance of the antenna�
●
Ensure sufficient heat dissipation at the installation location� The maximum
operating temperature indicated in the data sheet must not be exceeded�

If the installation instructions are not adhered to, the antenna characteristics
change� The DETE820 must be newly assessed at the mounting location�
