Antenna pattern ETSI
Directional radiation pattern ETSI
The directional radiation pattern is shown for nominal alignment and a center frequency of
866.3 MHz. The nominal antenna alignment is given when the antenna elevation is provided
as shown in the following figure.

Reference system
The half-power beam width of the antenna is defined by the angle between the two -3 dB
points. The range (in %) corresponding to the dB values in the patterns can be obtained from
this table .
Note that the measurements presented graphically below were carried out in a low-reflection
environment. Deviations can therefore occur in a normally reflecting environment.
