5 dBi Omni-directional Antenna
ANT24O5
Installation Guide
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.

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.

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.

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.
