6.5.6.2 Antenna radiation patterns in the FCC frequency band
Directional radiation pattern USA (FCC)
The directional radiation pattern is shown for nominal alignment and a center frequency of
915 MHz.
Figure 6-37 Reference system
The half-power beam width of the antenna is defined by the angle between the two -3 dB
points (corresponding to half the power referred to the maximum power). Which range (in %)
corresponds 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.
