lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna discharge
unit, connection to grounding electrodes, and requirements for the grounding electrode.
4.
Lightning - Avoid installation or reconfiguration of wiring during lightning activity.
5.
Power Lines - Do not locate an outside antenna system near overhead power lines or other electric
light or power circuits or where it can fall into such power lines or circuits. When installing an outside
antenna system, refrain from touching such power lines or circuits, as contact with them might be
fatal.
6.
Overloading - Do not overload wall outlets and extension cords as this can result in a risk of fire or
electric shock.
7.
