Placement and Other Important Considerations
Before installing your wireless antenna, observe the placement considerations.
Antenna placement dramatically affects potential coverage. Follow these
guidelines to maximize coverage:
• Place the antenna in a vertical position. Either right side up or up-side-down is
OK.
• Place the antenna in the middle of the coverage zone and at 1.5m or higher
above the floor.

v1.0, April 2008
Installation Guide for the 9 dBi Omni-directional Antenna ANT2409
• Minimize obstructions around the antenna. Ideally there shall be a visual line
of sight between the ANT2409 and the client antenna(s).
• High ceiling: place the ANT2409 in the center of the room installed up side
down on a pole or on the ceiling with the L shape bracket.
• Outdoors: Place the ANT2409 on a roof fixed on a pole 2m above the roof
level, or fixed directly on the roof near the edge, or against a wall, or on top of
a telephone box. In most of the cases one ANT2409 is sufficient because the
multipath fading is low or acceptable. However in cases where the building
density is high, or narrow streets, or direct echo from another building, etc.
two ANT2409 can improve the wireless performance (throughput and range).
This latter is applicable only if the wireless device has two RF ports.
• NOTE: Ground cable is not provided but is required. Use AWG 10, UL 1015,
Standard 600 V, 105°C, green or green/yellow insulation, 2 clips with a 5.5
mm inner diameter clamped at both ends, and cable no longer than 5 meters.
• Indoors: Place the ANT2409 above cubicle level, at the center of large room
area preferred attached to the ceiling, a pole, or a column. Ideally , it should be
located outside an IT data center or outside a room with multiple metal
partitions. Use a NETGEAR antenna cable of up to 10 m length to connect the
antenna to the wireless access point/router. In some situations one ANT2409
is sufficient because the multipath fading is low or acceptable and/or the client
adapter wireless node provide spatial diversity. However in other cases where
the multipath fading effect is medium to high two ANT2409 spaced by a few
meters can improve the wireless performance (throughput and range). This
latter is applicable only if the wireless device has two RF ports.
Indoor wireless propagation loss increases as follows:
– Wood building -- relatively little loss
– Floors in concrete -- some loss
– Reinforced concrete -- more loss
– Metal floor or reinforced concrete with a lot of metal pipes, metal air
conditioning channel, etc. -- most loss
• The best performance is achieved with a short cable between the antenna and
the wireless device. The shortest approved cable to be used in conjunction
with the ANT2409 in North America is the NETGEAR 1.5 m (ACC-10314-
01) cable.
• The antenna should be installed so that it is a minimum of 30 cm (12 inches)
away from people.

Installing the Wireless Antenna
There are two parts to the wireless antenna installation process:
• Assemble the wireless antenna for pole mount installation or flat surface
mount installation.
• Connect the appropriate electrical hardware depending on if the installation is
indoors or outdoors.
Follow the instructions in this section of the manual to install your antenna.
First, Assemble and Mount the Antenna
The antenna can be mounted vertically right-side-up or up-side-down.
1. Assemble the antenna as shown in the following illustration:
Chapter 2
Figure 2-1

v1.0, April 2008
Installation Guide for the 9 dBi Omni-directional Antenna ANT2409
2. Securely attach the antenna cable. Make sure to use the correct cable.
• Outdoors. Use the provided 2m antenna cable to connect to the lightning
arrestor. A seperate antenna must be purchased to connect the antenna to
the access point.
• Indoors. Use the provided N/SMA adapter with a NETGEAR cable
model ACC-10314-01, 02, 03, 04 or 05 (sold separately) to connect the
antenna to the access point. Do not use the provided 2m cable, which is
only for connecting to lightning arrestor in outdoor installation.
3. Mount the antenna as shown in the following illustrations. The antenna can be
pole mounted, wall mounted, or flat-surface mounted.

Now, Connect the Antenna
The instructions below cover outdoor and indoor installations.
Connecting the Antenna for and Outdoor Installation
1. Turn off your wireless unit.
2. In the procedure “Pole Mounting Configuration” on page 1-3, the ante nna
should have been assembled for outdoor installation using the provided 2meter cable. Connect the other side of the cable to the lighting arrestor as
shown here. You c an connect the cable to either of the two RF ports on the
lightning arrestor.

1. Connect the grounding cable (not included) from the lightning arrestor to th e
ground of the building.
Grounding cable: The grounding cable must be equivalent or better than:
AWG 10, UL 1015, Stranded, 600 V, 105
o
C, green or green/yellow
insulation, 2 clip of 5.5 mm inner diameter cramped at both ends, cable no
longer than 5 meters.
Warning: The lightning arrestor and appropriate ground cable must be
used for outdoor installation. NETGEAR does not assume
any responsibility in case of hazard resulting of noncompliance with these instructions.
2. Screw the N/SMA Reverse Adapter on the lightning arrestor (clockwise) on
the second RF port. Connect a NETGEAR cable model ACC-10314-01, 02,
03, 04 or 05 (sold separately) to the adapter.
3. Locate the primary detachable antenna on the wireless access point. Remove
the antenna and connect the other end of the NETGEAR cable ACC-1031401, 02, 03, 04 or 05 to this port.
Note: On access points with two antennas, if you are only replacing one
antenna, be sure to replace the primary antenna and do not
remove the secondary antenna
4. After attaching your new 9 dBi antenna(s), reconnect your wireless device to
the network and turn them on.
Connecting the Antenna for an Indoor Installation
In the procedure “First, Assemble and Mount the Antenna” on page 2-1, the
antenna should have been assembled for indoor installation using a NETGEAR
cable ACC-10314-01, 02, 03, 04 or 05 and the reverse N/SMA adaptor connected
to the antenna. The provided 2m cable should not have been used.
To connect the antenna:
1. Turn off your wireless unit.
