25 Outdoor Antenna Grounding — If an outside
antenna is connected to the product, be sure the
antenna is grounded so as to provide some
protection against voltage surges and built-up
static charges. Section 810 of the National
Electrical Code, ANSI / NFPA No. 70—1984,
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. See figure 1.
26 Lightning — For added protection of this product
during a lightning storm, or when it is left
unattended and unused for long periods of time,
disconnect it from the wall outlet and disconnect
the antenna. This will prevent damage to the
