2.7 DRU Antenna Options
Four
antennas,
shown
in
Figure

are
available
from
ADC
for
use
with
the
DRU.
All
antennas
include
a
6
foot
(1.8
m)
long
50-ohm
coaxial
cable
(equipped
with
SMA
male
connector)
for
connection
to
the
DRU.
The
DRU
is
equipped
with
an
SMA
female
connector
for
connecting
the
antenna
cable.
The
DRU
antennas
are
designed
for
unobtrusive
mounting
within
an
office
environment.
Each
type
of
antenna
provides
a
specific
coverage
pattern
in
order
to
accommodate
the
shape
of
the
area
where
coverage
is
required.
The
ceiling-mount
omnidirectional
antenna
provides
2.5
dBi
of
gain
and
is
designed
to
mount
in
the
center
of
the
coverage
area.
The
directional
panel
antenna
provides
8
dBi
of
gain
and
is
designed
to
mount
vertically
on
one
side
of
the
coverage
area.
The
90º
panel
antenna
provides
7.5
dBi
of
gain
and
is
designed
to
mount
vertically
in
the
corner
of
the
coverage
area.
The
ceiling
mount
hallway
antenna
provides
4
dBi
of
gain
and
is
designed
to
mount
in
the
center
of
long
corridors.
Other
antennas
other
than
those
offered
by
ADC
may
also
be
used
if
required.
Note:
To
comply
with
Maximum
Permissible
Exposure
(MPE)
requirements,
antennas
must
be
installed
to
provide
at
least
20
centimeters
of
separation
from
all
persons
per
FCC
47
CFR
part
2.1091.
