Antenna Information; Outdoor Antenna Grounding - NAD C 425 Owner's Manual

ANTENNA INFORMATION

If an indoor antenna is used (either built into the set or installed separately),
never allow any part of the antenna to touch the metal parts of other
electrical appliances such as a lamp, TV set etc.
CAUTION POWER LINES
Any outdoor antenna must be located away from all power lines.

OUTDOOR ANTENNA GROUNDING

If an outside antenna is connected to your tuner or tuner preamplifier, be
sure the antenna 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 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.
a. Use No. 10 AWG (5.3mm2) copper, No. 8 AWG (8.4mm2) aluminium,
No. 17 AWG (1.0mm2) copper-clad steel or bronze wire, or larger, as a
ground wire.
b. Secure antenna lead-in and ground wires to house with stand-off
insulators spaced from 4-6 feet (1.22 - 1.83 m) apart.
c. Mount antenna discharge unit as close as possible to where the leadin
enters house.
d. Use jumper wire not smaller than No.6 AWG (13.3mm2) copper, or the
equivalent, when a separate antenna-grounding electrode is used. see
NEC Section 810-21 (j).
EXAMPLE OF ANTENNA GROUNDING AS PER NATIONAL ELECTRICAL
CODE INSTRUCTIONS CONTAINED IN ARTICLE 810 - RADIO AND
TELEVISION EQUIPMENT.
NOTE TO CATV SYSTEM INSTALLER: This reminder is provided to call
the CATV system installer's attention to Article 820-40 of the National
Electrical Code that provides guidelines for proper grounding and, in
particular, specifies that the ground cable ground shall be connected to
the grounding system of the building, as close to the point of cable entry
as practical.
