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
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, see page 9.

ANT24O5
Placement and Other Important Considerations
In order to maximize coverage, antennas must be placed in a good spot. A lot of improvement
can be achieved by optimizing the line of sight between antennas. Try to minimize the
partitions and partial obstructions if possible. For instance, place the antenna on a wall above
the cubicles (cubicles generally include a metal foil). Ideal placement is against a wall, 2m high,
or on the ceiling facing the area to cover.

Figure 2: Optimal antenna placement on an interior wall
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.

coverage area
Figure 1: Optimal antenna placement on the ceiling
The longer the antenna cable, the higher the attenuation, or signal loss. This will decrease the
range and performance. The best performance is achieved with 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.
If the wireless access point, router or gateway is in a IT room, place the antenna outside of the
room close to the ceiling against a wall. Use a NETGEAR antenna cable of up to 10 meters in
length to connect the antenna to the wireless access point.
