RF Safety Notice
(English and French)
Concentrated energy from a directional antenna may pose a health hazard to
humans. Do not allow people to come closer to the antenna than the distances
listed in the table below when the transmitter is operating. More information on
RF exposure can be found online at the following web site:
www.fcc.gov/oet/info/documents/bulletins .

Antenna Gain vs. Minimum RF Safety Distance
Antenna Gain
0–5 dBi 5–10 dBi 10–16.5 dBi
Safety Distance (SD4) 0.93 meter 1.66 meters 3.51 meters
Safety Distance (SD9) 0.72 meter 1.28 meters 2.71 meters
Safety Distance (SD1)
For SD1, maintain an RF safety distance of
2.02 meters for a 7 dBd (9.15 dBi) antenna.
Use of higher gain antennas means
increasing the distance accordingly.
Safety Distance (SD2)
For SD2, maintain an RF safety distance of
1.89 meters for a 7 dBd (9.15 dBi) antenna.
Use of higher gain antennas means
increasing the distance accordingly.
Safety Distance
(Other SD models): Consult factory prior to operation.
