If an outside antenna is connected to the television
equipment,
be sure the antenna system is
grounded so as to provide some protection against voltage surges and built-up static charges.
Section 810 of the National Electrical Code 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 elec-
trodes, and requirements
for the grounding
electrode.
