Warranty/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, or 04 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 ANT24D18 antenna should only be used with devices that have been FCC  
approved for use with it. Please check the NETGEAR web site at  
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

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.  
Wall Mount Configuration With Fixed Brackets  
This illustration shows the wall mount configuration with fixed brackets.  
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.  
Placement and Other Important Considerations  
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.  
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).  
-
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.  
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:  
-
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.  
-
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.

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.  
Installing the 18 dBi Patch Panel  
Directional Antenna  
2
There are two parts to the wireless antenna installation process:  
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.  
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.  
The antenna should be installed so that it is a minimum of 50 cm (20 inches) away  
from people.  
Follow the instructions in this section of the manual to install your antenna.

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  
this port.

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.  
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.  
If the wireless device transmits only with the primary antenna port, the 2 ANT24D18  
antennas can be used only for spatial diversity.  
7. After attaching your new 18 dBi antenna(s), reconnect your wireless device to the network  
and turn it on.  
Spatial diversity: place the 2 antennas 3 to 9 feet away and oriented toward the
