nating-current line plug (a plug having one
blade wider than the other). This plug will fit
into the power outlet only one way. This is a
safety feature. If you are unable to insert the
plug fully into the outlet, try reversing the
plug. If the plug should still fail to fit, contact
your electrician to replace your obsolete
outlet. Do not defeat the safety purpose of
the polarized plug.

15. Outdoor Antenna Grounding. If an outside
antenna or cable system is connected to the
product, be sure the antenna or cable
system is grounded so as to provide some
protection against voltage surges and built-
up static charges. Article 810 of the National
Electrical Code, ANSI/NFPA 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 Figure 1.

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.
