ANTENNA CONNECTIONS
Grounding an Outdoor
Antenna
If the tuner is used with an
outdoor antenna, the anten-
na must be grounded
against static charges and
voltage surges. Consult the
instructions that came with
the antenna or contact the
antenna manufacturer for
proper installation instruc-
tions. The adjacent dia-
gram gives a general
depiction of how an out-
door antenna should be
grounded. For complete
guidelines on antenna
grounding procedures,
please consult the National
Electrical Code, Section
810, ANSI/NFPA No. 70-
1984.
