Antenna
The device is equipped with an internal antenna. Good reception conditions exist
when the front of the device is oriented centered to the remote device with which
the radio link is to be established.
Figure 9: Aligning the device
The alignment characteristic for the internal antenna is primarily relevant for links
in the open field and over long distances. When operating the device at short
distances, inside buildings or without line-of-sight links structural conditions are
the decisive factor for good reception.
As the device comes equipped with a circular polarized antenna, rotation of the
device around the link axis between the local and remote device does not have any
adverse impact on link quality.
The directional alignment (antenna) diagrams for the antenna are given in the
following figures for a frequency of 2.45 GHz.
