1 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: • 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. • 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.
