Extension
Aerials
When
using
the
RF
‐
AERIAL
‐
PM2
or
RF
‐
AERIAL
‐
PM5
extension
aerials,
it
is
important
to
observe
some
basic
rules
for
siting
and
mounting.
1.
Always
ensure
there
is
a
much
clear
space
around
the
aerial
as
possible.
2.
Generally
speaking,
where
possible
mount
the
aerial
as
high
as
possible
on
the
same
floor
as
the
routers
and
EDs
3.
Don’t
mount
between
metal
surfaces
(for
example
steel
I
‐
beams)
in
ceiling
spaces
4.
Wherever
possible,
mount
the
aerial
on
a
metal
ground
plane
(such
as
the
top
of
a
metal
panel)
5.
The
coaxial
cable
used
for
the
RF
‐
AERIAL
‐
PM2
or
RF
‐
AERIAL
‐
PM5
extension
aerials
is
semi
‐
rigid
and
should
not
be
bent
at
too
sharp
an
angle
or
too
tight
a
radius.
It
is
recommended
that
the
minimum
bending
radius
is
5cms
6.
Always
mount
the
aerial
vertically.
This
produces
the
optimum
radiation
pattern
and
signal
strength
7.
Extension
aerials
can
be
used
with
receivers
and
RF
‐
IOM
modules.
8.
Aerial
extensions
should
not
exceed
5m
to
prevent
excessive
loss
of
signal.
