Summary
In order the keep the RF exposure within the FCC limit, it is necessary to maintain the safe distance from
the antenna. The results shown in Figures 1, and 2 can be summarized in the following table:
Minimum permissible distance from antenna (cm)
Antenna Gain
(dBi)
Digital Mode (5W) Analog Mode (6W)
0 20 30
5 40 60
16 140 200
30 700 960
Notice the above table indicates worst-case situation (straight in front of the antenna).
