5 dBi Omni-directional Antenna ANT2405

Note: For optimal results in extending wireless range with antenna installations, consult a
qualified professional installer service for a site survey and proper installation. For a list of
devices approved by the FCC for use with the antenna, see the NETGEAR website at
http://tools.netgear.com/legal/fcc_antennas.html.

Package Contents

The package includes:

• NETGEAR 5 dBi Omni-directional Antenna
ANT2405 including a 10 cm RG316 cable with a
reverse SMA connector for IEEE 802.11b or 802.11g
wireless devices

• Ceiling/wall mount bracket hardware

• Warranty card

• Support information card

Antenna Cable

The longer the antenna cable, the higher the signal loss (attenuation). This decreases range
and performance. For best performance, use a short cable between the antenna and the
wireless device. The shortest FCC-approved antenna cable is the NETGEAR 1.5 M
(ACC-10314-01) cable. For optimal performance, use a low-loss NETGEAR antenna
cable up to 10 meters long.

Antenna Placement and Location

To maximize coverage and performance, place the antenna within the line of sight of your
wireless devices. Try to minimize partitions and objects that block the line of sight if
possible.

• For a ceiling installation, place the antenna in the middle of the coverage area.

• For a wall installation, place the antenna on an interior wall above cubicles (cubicles
generally include a metal foil). Ideal placement is 2 meters high.

Installing the Antenna

Turn off your wireless access point, and connect your ANT2405 antenna. If your wireless
access point is new, follow the access point installation instructions. If you are upgrading
an existing access point, turn it on again.

Specifications for 10 cm RG316 Antenna Cable (Included in the Package)

Type RG316

Length 10 cm (3.9 in)

External diameter 2.5 mm

Impedance 50 +/- 5 Ohms

SWR 1.5 maximum

Loss 138 dB/100 m (42 dB/100 ft) at 2.4 GHz

Minimum bend radius 2.5 mm (1 in)

Approximate
coverage area

• If the wireless access point, router, or gateway, is in an IT room, place the antenna
outside the room against a a wall and close to the ceiling.

The area close to, behind, or beside the antenna will be covered, because the dynamic
range of the WLAN transmitter/receiver and antenna is approximately 100 dB. Even with
20 dB to 40 dB or attenuation, the signal strength is still strong and communication is
maintained.

Federal Communications commission (FCC) Compliance Notice: Radio Frequency
Notice

This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions:

1. This device may not cause harmful interference.

2. This device must accept any interference received, including interference that may cause
undesired operation.

To comply with FCC regulations, the ANT2405 should only be used with devices that have been
FCC approved for use with the NETGEAR ANT2405. Check the NETGEAR website at http://
tools.netgear.com/legal/fcc_antennas.html for an updated list of FCC approved devices.

Note: This equipment has been tested and found to comply with the limits for Class B digital
devices, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in residential installation. This equipment generates, uses,
and can radiate radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the interference by one or more of the
following measures: (1) Reorient or relocate the receiving antenna; (2) Increase the separation
between the equipment and receiver; (3) Connect the equipment to an outlet or circuit different from
that to which the receiver is connected; (4) Consult the dealer or an experienced radio/TV technician
for help.

FCC and EU Radiation Exposure Statement

This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. To avoid the possibility of exceeding the FCC radio frequency exposure limits, human
proximity to the antenna must be less than 20 cm (8 inches) during normal operation.

This device should not be co-located with other transmitters.
For EU, use of any antenna requires careful planning and extra considerations to comply with EU

emissions and health standards and regulations. Antenna installation must comply with the
maximum level authorized by each country.
