7.POWER-CORD PROTECTION - Power supply cords should be routed
so that they are not likely to be walked on or pinched by items placed
upon or against them, paying particular attention to cords at plugs,
convenience receptacles, and the point where they exit from the
appliance.
8.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

11.OUTDOOR ANTENNA GROUNDING - If an outside antenna or cable
system is connected to the unit, be sure the antenna or cable system is
grounded to provide some protection against voltage surges and
built-up static charges. Section 810 of the National Electrical Code,
ANSI/NFPA 70, provides information with respect 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.
