CMM4
1
Ensure
that
the
mounting
position:
•
is
not
farther
than
328
feet
(100
meters)
from
the
furthest
AP
or
BH
that
the
CMM4
will
serve.
•
is
not
closer
than
10
feet
(3
meters)
to
the
nearest
AP
or
BH.
•
is
not
further
than
100
feet
(30.5
meters)
of
cable
from
the

antenna.
•
allows
the
doors
to
open
fully
open
for
service.
2
Select
a
support
structure
to
which
the
flanges
can
be
mounted.
3
If
the
support
structure
is:
•
a
wall,
use
screws
or
bolts
(neither

to
attach
the
flanges
to
the
wall.
•
an

object,
use
adjustable
stainless

(provided)
to
attach
the
CMM4
to
the
object.
•
a
pole
that

an
outside

If
the
CMM4
is
mounted
to
a
non-conducting
structure
(cinder
block
wall,
for
example)
or
there
is
any
doubt
as
to
a
good
ground
through
the
structure,
run
a
10
A
WG
ground
cable
from
one
of
the
Ground/Earth
terminations
of
one
of
the
terminal
blocks
inside
the
CMM4,
through
a
cable
gland,
and
to
known
good
ground.
