Placing the Omni-Directional Antenna
Because the antenna is omni-directional, you have more flexibility with where you
can place the access point. Keep in mind, however, that the Omni-Directional
Antenna achieves its peak gain when your client PC (that is, a PC with a wireless
adapter) stays on the same horizontal plane as the Antenna.

Line of sight—The minimum requirement is line of sight. If you can see the
receiver antenna, then you are within a suitable range.

•
Avoid obstacles—Avoid obstacles and set up the Omni-Directional Antenna
and the other antennas as high as possible. Try to avoid trees, buildings, and
other objects close to the path between two antennas, because they can
reduce signal power.

Using the Omni-Directional Antenna
The Omni-Directional Antenna can be used with the access point for several
purposes:
purposes:
•
Access point to client devices—You can achieve better range and
transmission with the Omni-Directional Antenna when connecting the
wireless client (a PC with any wireless adapter) to the access point.

•
Repeater mode—The Omni-Directional Antenna and access point can
repeat wireless signals from one access point to other devices, such as to a
client PC or to other repeaters.

client PC or to other repeaters.
•
Point-to-multipoint bridging—The Omni-Directional Antenna connects to
one main access point. The main access point connects to other access
points that each use a separate Directional Antenna. To achieve maximum
distance coverage, the other access points are usually located in different
directions from the main access point.

NOTE
The Omni-Directional Antenna does not provide extra value for point-to-point
bridging. You can achieve the same antenna gain by using the internal directional
antenna from the access point.
