• 2-meter low loss antenna cable to connect the antenna to a lightning arrestor
• Lightning Arrestor
NOTE: a ground cable is not included but required for outdoor installation. The grounding
cable must be equivalent or better than: AWG 10, UL 1015, Stranded, 600 V, 105 oC, green or
green/yellow insulation, 2 clip of 5.5 mm inner diameter cramped at both ends, cable no longer
than 5 meters.
• Reverse N/SMA Adapter
• Antenna mounting assembly (tube, grommet, 2 brackets, screws, washers)
• L shape bracket for top & ceiling mounting
• Screws, bolts, washers, U-bolts and plastic anchors
• Installation Guide
• Warranty and Support Information card
If any of the parts are incorrect, missing, or damaged, contact your NETGEAR dealer. Keep the
carton, including the original packing materials, in case you need to return the product for repair.
Antenna cable for connecting the wireless device is sold separately. Please use a NETGEAR
model ACC-10314-01, 02, 03, 04, or 05 cable.
To obtain optimal results in extending wireless range with antenna installations, consult a qualified
professional installer for site survey and installation assistance.
In the U.S., the ANT2409 antenna should only be used with devices that have been FCC approved
for use with it. Please check the NETGEAR web site at
http://www.NETGEAR.com/go/antennas_fcc for an updated list of FCC approved devices.
For Europe, use of any antenna requires careful planning and extra consideration to comply with
EU emissions and health standards and regulations. Antenna installation must comply with the
maximum level authorized by each country. Please check the NETGEAR web site
at http://www.NETGEAR.com/go/antennas_eu for a list of restrictions and approved devices.

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 ANT2409 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.
• 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

Installation Guide for the 9 dBi Omni-directional Antenna ANT2409
1-6 Getting Started with the ANT2409
• 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.

Chapter 2
Installing the 9 dBi Omni-directional 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.

2-2 Installing the 9 dBi Omni-directional Antenna
First, Assemble and Mount the Antenna
Figure 2-1: Antenna Assembly and Mounting
Step Procedure
Step 1 Feed the antenna cable through the antenna
mounting assembly.
Note: Use the correct cable.
•Outdoors: use the provided 2m antenna
cable.
•Indoors: use the provided N/SMA adapter
with a Netgear cable model
ACC-10314-01, 02, 03, 04 or 05 (sold
separately). For indoors, do not use the
provided 2m cable.
Step 2 Securely attach the antenna cable by screwing
it onto the antenna.
Step 3 Insert the antenna into the mounting assembly.
Step 4 Position the key slot on the antenna so that it
is aligned with the mounting screw hole
illustrated in step 5.
Step 5 Tighten the mounting screw so that it fits in the
key slot on the antenna.
Step 6 Attach the assembled antenna to the mounting
surface with the appropriate hardware (U-bolts
for pole mount, L-bracket or no bracket for flat
mount).
Note: The antenna can be mounted vertically
right-side-up or up-side-down.

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 “First, Assemble and Mount the Antenna” on page 2-2, the antenna should
have been assembled for outdoor installation using the provided 2-meter cable. Connect the
other side of the cable to the lighting arrestor as shown here. You can connect the cable to
either of the two RF ports on the lightening arrestor.

3. Connect the grounding cable (not included) from the lightning arrestor to the ground of the
building.
Grounding cable: The grounding cable must be equivalent or better than: AWG 10, UL 1015,
Stranded, 600 V, 105 oC, 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
non-compliance with these instructions.
4. 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.
5. Locate the primary detachable antenna on the wireless access point. Remove the antenna and
connect the other end of the NETGEAR cable ACC-10314-01, 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.
6. After attaching your new 9 dBi antenna(s), reconnect your wireless device to the network and
turn them on.
