NETGEAR ANT24O5 Installation Manual

Introduction

This section introduces the package contents of the NETGEAR 5 dBi Omni-directional
Antenna ANT24O5 and related components.

NOTE: To obtain optimal results in extending wireless range with antenna installations, it is
recommended that a qualified professional installer service is consulted for site survey and
proper installation.

To comply with FCC rules the ANT24O5 antenna should only be used with devices that
have been FCC approved for use with the ANT24O5. Please check the NETGEAR web site
at http://www.NETGEAR.com/go/antennas_fcc for an updated list of FCC approved devices.

For EU, 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.

Package Contents

The package should contain:

• NETGEAR 5 dBi Omni-directional Antenna ANT24O5 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

Figures 1 and 2 show where one could place the ANT24O5 for best coverage in an office. In
Figure 1, the ANT24O5 is placed on the ceiling in the middle of the area to cover. In Figure 2,
the ANT24O5 is placed in an elevated location on an interior wall, above and facing the
indoor coverage. Notice that the area close to the antenna, behind or beside it, will still be
covered because the dynamic range of the WLAN transmitter/receiver and antenna is
approximately 100dB. So, even with 20dB to 40dB of attenuation, the signal strength is still
strong and communication is maintained.

Statement of Conditions

In the interest of improving internal design, operational function, and/or reliability, NETGEAR reserves the right to
make changes to the products described in this document without notice. NETGEAR does not assume any liability
that may occur due to the use or application of the product(s) or circuit layout(s) described herein.

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.

Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to
part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a
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 into an
outlet on a circuit different from that to which the receiver is connected, (4) Consult the dealer or an experienced
radio/TV technician for help.

Federal Communications Commission (FCC) Radiation Exposure Statement

This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. In order to
avoid the possibility of exceeding the FCC radio frequency exposure limits, human proximity to the antenna shall not
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 consideration to comply with EU emissions and health
standards and regulations. It is recommended that a qualified professional installer service is consulted for site survey
and proper installation. Antenna installation must comply with the maximum level authorized by each country.
