70, provides information with regard to proper grounding of
the mast and supporting structure, grounding of the 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. See the figure below.
14 Lightning — For added protection for this video product
receiver during a lightning storm, or when it is left unattended
and unused for long periods of time, unplug it from the wall
outlet and disconnect the antenna or cable system. This will
prevent damage to the video product due to lightning and
power-line surges.
15 Power Lines — An outside antenna system should not be
located in the vicinity of 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,
extreme care should be taken to keep from touching such
power lines or circuits as contact with them might be fatal.
