OUTDOOR ANTENNA GROUNDING

it an amslda antenna ts connected to vour tuner or tuner-preamplifier, be
sure the antenna system Is grounded so as to provlda some protection
agalnst voltage surges and built-up static charges. Section 810 at the
National Electrical Code. ANSI/NFPA No, 704984. provides inlormation with
respect to proper grounding ot the mast and suooonlng structure. grounding
of the lead-in wire to an antenna discharge unit, size at grounding
conductors. location of antenna discharge unit, connection to grounding
electrodes. and requirements for the grounding electrode.

a. Use No.10 AWG (5.3 mm-) copper. No.6 AWG (6.4 mm') aluminum.
No.17 AWG (1.0 mm-) copper-clad steel or bronze wire. or larger. as a
ground wire.

n Stamina antenna lead-in and around wires to house wtth stand-oft
Insulators spaced from 4-6 feet (1.22-1.83 m) apart.

o. Mount antenna discharge unit as close as possible to where lead-in
enters house.

d. Use Jumper wire not smaller than No.6 AWG (13.3 mm?) copper, or the
equivalent, when a separate antenna-grounding electrode is used. See NEC
Section 810-21 (j).

NOTE TO CATV SYSTEM INSTALLER

ThIs reminder Is proVIded to cal the CATV system Installers attention to
Article 820-22 ot the National Electrical Code that prowdes gmdelmes for
proper grounding and. in particular. specttIes that the cable ground shall be
connected to the grounding system of the building, as close to the pomt ot
cable entry as practical.
