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.

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.
