-More range: Use the 18 dBi one side with short antenna cable. For instance WG302,
1.5m cable ACC-10314-01, lightning arrestor, 2m cable, and ANT24D18 on one
side and WG302 (with own antennas) on the other side.
-Super range: Use the 18 dBi both side with short/medium antenna cable. For instance
WG302, 3m cable ACC-10314-02, lightning arrestor, 2m cable, and ANT24D18 on
both sides.
-Super extra range, 802.11b only: Use the 18 dBi and booster ANT24BNA both side
with short/medium antenna cable. For instance ME103, 3m cable ACC-10314-02,
11b booster ANT24BNA, 1.5m cable ACC-10314-01, lightning arrestor, 2m cable,
and ANT24D18 on both sides.
• Outdoor point-to-point alternative, antennas indoor behind windows: Place the 18 dBi indoor
behind a clean window (no metal coating) in both buildings and facing each other. Use a
short/medium antenna cable and fix the antenna on a tripod. Alternatively the 18 dBi can
be placed on a wall just behind the window (no more than 3 meters (10 ft)). Furthermore
the antennas should be located high in the building close the top. One example: WG302,
3m cable ACC-10314-02 and ANT24D18 on both sides. Please account for less range
than outdoor (30-70% less range).
Outdoor 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 antenna on a wall or pole, facing the area to cover at 2 meters or higher
above the floor. Place the ANT24D18 above cubicle level with the maximum open space
in its front. 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.
-Indoor bridging in an airport terminal, train station terminal, warehouse, exhibition
hall: Highest indoor range can be achieved when there is a good visual line of sight
and maximum open space in between the antennas. One example: WG302, 3m cable
ACC-10314-02 and ANT24D18 on both sides. Can greatly increase range vs. 2
WG302 only.
-Indoor bridging where there is less than 15 ft open space (narrow hall, large room
office with low ceiling): WLAN communication can suffer from multiple reflections
which are environment, orientation and time dependent, called multipath fading. In
this case. 2 ANT24D18s per wireless node (requires both primary and secondary RF
ports) can improve the range and throughput by providing spatial diversity.

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 ANT24D18 in a vertical position, connector toward the bottom.
•Minimize the obstructions in the front of the antenna. There should be a good visual line
of sight and maximum open space between the ANT24D18 and the other antenna(s).
•Outdoor point-to-point application (bridging, repeater mode, building to building, etc.):
Miles of outdoor range can be obtained when the antennas are installed properly. Fix the
antenna on the top of a building on a pole or on an external wall. Provide a good visual
line of sight between the ANT24D18 and the other antenna (max. open space) and ideally
no partial obstruction. Coverage increases as follow:
-Use the 18 dBi one side with long antenna cable. For instance WG302, 10 m cable
ACC-10314-04, lightning arrestor, 2m cable, and ANT24D18 on one side and
WG302 (with own antennas) on the other side.

Installing the 18 dBi Patch Panel
Directional Antenna
There are two parts to the wireless antenna installation process:
•Mount the antenna on a pole, or on a wall with adjustable brackets, or on a wall with
fixed brackets.
• 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, Mount the Antenna
Pole Mount Installation
Warning, Indoor point to multipoint: the ANT24D18 is not omnidirectional and is not
suitable when low ceilings, partial obstructions, walls, cubicles, large metal objects, etc. are
present. WLAN communications can suffer from multiple reflections, which are
orientation, environment and time dependent.
• 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 ANT24D18 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 50 cm (20 inches) away
from people.

Now, Connect the Antenna
The instructions below cover outdoor and indoor installations.
Connecting the Antenna for an Outdoor Installation
1. Turn off your wireless unit.
2. Connect the provided 2-meter cable to the antenna and to the arrestor as shown here. You
can connect the cable to either of the two RF ports on the lightning 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°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
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

4. Locate the primary detachable antenna of the wireless device. Remove the antenna and
connect the other end of the NETGEAR cable ACC-10314-01, 02, 03 or 04 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.
5. If connecting 2 ANT24D18 antennas: repeat step 2 to 4 for the second antenna and
connect it the secondary port. If the wireless device supports transmit/receive on both
ports, the 2 antennas can be used to cover 2 separate or partial overlapping WLAN areas.
For instance the 2 ANT24D18 antennas could be oriented at 90 degrees and positioned
50 feet away and using the WG302 access point. The 2 antennas can also be used to
provide spatial diversity.
If the wireless device transmits only with the primary antenna port, the 2 ANT24D18
antennas can be used only for spatial diversity.
Spatial diversity: place the 2 antennas 3 to 9 feet away and oriented toward the
same direction.
6. After attaching your new 18 dBi antenna(s), reconnect your wireless device to the network
and turn it on. The provided 2m cable and lightning arrestor should not have been used.
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. If connecting 2 ANT24D18 antennas: repeat step 2 to 5 for the second antenna and
connect it the secondary port. If the wireless device supports transmit/receive on both
ports, the 2 antennas can be used to cover 2 separate or partial overlapping WLAN areas.
For instance the 2 ANT24D18 could be oriented at 90 degrees and positioned 50 feet
away and using the WG302 access point. The 2 antennas can also be used to provide
spatial diversity.
If the wireless device transmits only with the primary antenna port, the 2 ANT24D18
antennas can be used only for spatial diversity.
Spatial diversity: place the 2 antennas 3 to 9 feet away and oriented toward the same direction.
7. After attaching your new 18 dBi antenna(s), reconnect your wireless device to the network
and turn it on.
