FM
antennas
Your

sensitivi-
ty.
However,
the
performance
of
your
system
is
determined
toa
very
large
extent
upon
the
signal
conditions
where
the
antenna
is
placed.
The
reason
is
that
FM
broadcast
signals
travel
in
straight
paths.
Therefore
they
can
be
blocked
by
natural
or
man-made
obstructions
such
as
mountains,
hills,
or
buildings.
At
large
distances
from
the
transmitter
the
curvature
of

earth
acts
as
a
screen
between

and
receiver.
Consider
the
signa!
conditions
in
planning
your
installation.
If
you
live
in
or
near
an
urban
area
the
indoor
antenna
(supplied)
may
serve
your
needs
adequately.
However,
if
favorite
stations
are
weak
due
to
natural
obstructions,
or
if
you
live
in
a
building
which
is
made
of
steel-reinforced
concrete
(which
acts
as
a
shield)
it
may
be
necessary
to
install
a
good
outdoor
antenna.
FM
outdoor
antenna
Consult
with
your
dealer
or
service
man
about
the
best
method
of
selecting
and
erecting
an
outdoor
FM
antenna.
The
choice
of
lead-in
(feeder)
wire
is
also
important,
The
flat
ribbon-shaped
twin
lead
performs
well
electrically,
is
cheaper
and
is
somewhat
easier
to
handle
in
routing
through
windows
and
around
rooms.
Coaxial
cable
is
more
expensive,
does
a
much
better
job
of
minimizing
interfer-
ence,
is
less
prone
to
the
effects
of
weather
and
close-by
metal
objects,
and
is
nearly
as
good
a
signal
conductor
as
the
ribbon
type
wire.
The
latter
is
particularly
true
of
foam-type
coaxial
cables.
Coaxial
cable
is
somewhat
more
difficult
to
install
at
the
point
where
the
cable
enters
the
building.
If
coaxial
cable
is
selected,
make
sure
the
antenna
is
designed
to
drive
that
type
of
cable.
©
To
minimize
auto-ignition
noise,
locate
the
antenna
as
far
from
heavy
traffic
as
possible.
@
Keep
the
feeder
or
coaxial
cable
as
short
as
possible.
Do
not
bundie
or
roll
up
excess

The

at
