PLEASE READ THESE SAFETY PRECAUTIONS
RF Energy Health Hazard
Professional installation required. The radio equipment described in this guide uses radio
frequency transmitters. Although the power level is low, the concentrated energy from a
directional antenna may pose a health hazard.
Use the following chart for determining the minimum safe distance. Do not allow
people to come within the minimum safe distance of the antenna while the
transmitter is operating.
Peak Gain of
Antenna
Minimum
Safe Distance
18 dBi 20 cm
20 dBi 20 cm
23 dBi 25 cm
25 dBi 32 cm
30 dBi 56 cm
37.6 dBi 135 cm
Protection from Lightning
Article 810 of the US National Electric Department of Energy Handbook 1996 specifies
that radio and television lead-in cables must have adequate surge protection at or near the
point of entry to the building. The code specifies that any shielded cable from an external
antenna must have the shield directly connected to a 10 AWG wire that connects to the
building ground electrode.
