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 ANT24D18v2 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 ANT24D18v2 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 ANT24D18v2 and the other antenna (max. open space) and ideally
no partial obstruction. Coverage increases as follow:
- Use the 14 dBi one side with long antenna cable. For instance WG302, 10 m cable
ACC-10314-04, lightning arrestor, 2m cable, and ANT24D18v2 on one side and
WG302 (with own antennas) on the other side.

- More range: Use the 14 dBi one side with short antenna cable. For instance WG302,
1.5m cable ACC-10314-01, lightning arrestor, 2m cable, and ANT24D18v2 on one
side and WG302 (with own antennas) on the other side.
- Super range: Use the 14 dBi both side with short/medium antenna cable. For instance
WG302, 3m cable ACC-10314-02, lightning arrestor, 2m cable, and ANT24D18v2 on
both sides.
Outdoor point-to-point alternative, antennas indoor behind windows: Place the 14 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 14 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 ANT24D18v2 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 ANT24D18v2 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 ANT24D18v2 on both sides. Can greatly increase range vs. 2
WG30 2 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 ANT24D18v2 per wireless node (requires both primary and secondary RF
ports) can improve the range and throughput by providing spatial diversity.
