an outside antenna system to keep from
touching
power
lines
or
circuits, as contact with
them may
be
fatal.
Do
not
install external
antennas
near overhead power
lines
or other
electric light
or
power circuits, nor where an antenna can
fall
into
such circuits
or
power
lines.

Ground
all
outdoor
antennas-
If
an
external
antenna

be
sure the antenna

grounded. This will
provide some protection against
voltage
surges and
built-up
static charges.
