availability
and

the
antenna
must;
•
be
clear
and
free
of
obstructions
•
be
clear
of
metal
objects
•
be
located
away
from

Installing
Antenna
Cables
When
installing
antenna
cables,
follow
these
guidelines:
•
Route
and
restrain
cables
to
prevent
them
from
vibrating
or
moving
under
normal
conditions,
which
could
result
in
damage
to
the
antenna
or
the
coaxial
cable
connections.
•
Wherever
the
cables
contact
structures,
protect
the
cables
from
chafing
or
abrasion.
If
a
cable
needs
to
be
bent,
avoid
kinking
it,
and
ensure
that
each
bend
radius
follows
the
cable
supplier
limits.
•
Use
coaxial
sealant,
shrink
‐
wrap
tubing,
electrical
tape,
or
another
suitable
product
to
seal
all
cable
connections
appropriately
to
prevent
moisture
and
corrosion
damage
from
weather
exposure.
•
Mount
all
antennas
vertically
and
clear
of
nearby
metal
obstructions
•
Minimize
horizontal
obstructions
as
much
as
possible
because
they
can
create
areas
of
poor
system
coverage.
•
To
minimize
the
loss
of
radio
signal
from
the
antenna
to
the
terminal,
the
specific
coaxial
cable
system
between
the
antenna
and
the
other
component
should
be
less
than
3db
including
connector
loss.

Antenna
Installation
The
ideal
position
for

vehicle
‐

is
to
capitalise
on
the

ground
plane
from
the
surface
of

Marine
Antenna
Installation
The
antenna
must
be
installed
without
obstruction
of
other
instruments
or
structures.
The
antenna
must
not
be
positioned
within
range
of
radar
equipment
or
other
RF
interference.
Fixed
Site
Installation
The
antenna
must
be
installed
without
obstruction
of
other
buildings,
chimneys
or
other
structures.
Consideration
should
also
be
given
to
the
surrounding
environments
such
as
large
trees,
mountains
or
other
buildings.
