Antenna spacing requirements for user safety
It is important to keep the radio's antenna a safe distance from the user. To meet the requirements of FCC part
2.1091 for radio frequency radiation exposure, this radio must be used in such a way as to guarantee at least 20
cm between the antenna and users. Greater distances are required for high-gain antennas. The FCC requires a
minimum distance of 1 mW *cm2 power density from the user (or 20 cm, whichever is greater).
If a specific application requires proximity of less than 20 cm, the application must be approved through the FCC
for compliance to part 2.1093.
