Installation Notes
Because antennas transmit and receive radio signals, they are susceptible to RF obstructions and common sources of interference that can reduce throughput and range of the device to which they are connected. Follow these guidelines to ensure the best possible performance:
???Mount the antenna to utilize its propagation characteristics. A way to do this is to orient the antenna horizontally as high as possible at or near the center of its coverage area.
Note The antenna must be mounted horizontally in order to maximize its omnidirectional propagation characteristics. Mounting it vertically may noticeably decrease the antenna???s range and overall performance.
???Keep the antenna away from metal obstructions such as heating and
???The density of the materials used in a building???s construction determines the number of walls the signal must pass through and still maintain adequate coverage. Consider the following before choosing the location to install your antenna:
???Paper and vinyl walls have very little affect on signal penetration.
???Solid and

Installation Notes
???Concrete and wood block walls limit signal penetration to three or four walls.
???A signal can penetrate five or six walls constructed of drywall or wood.
???A thick metal wall causes signals to reflect off, causing poor penetration.
???A chain link fence or wire mesh spaced between 1 and 1 1/2 in. (2.5 and 3.8 cm) acts as a harmonic reflector that blocks a 2.4 Ghz radio signal.
???Install the antenna away from microwave ovens and
???Install the antenna horizontally to maximize signal propagation.
Installation Notes
This antenna is designed to be mounted indoors on a suspended ceiling track having either flush or recessed mounted ceiling tiles.
Safety Instructions
Follow these safety instructions when installing your antenna.
???Plan your installation procedure carefully and completely before you begin.
???If you are installing an antenna for the first time, for your own safety as well as others, seek professional assistance. Consult your dealer, who can explain which mounting method to use for the location where you intend to install the antenna.
???Select your installation site with safety, as well as performance, in mind. Remember that electric power cables and telephone lines look alike. For your safety, assume that any line is an electric power line until determined otherwise.
???Call your local power company or building maintenance organization if you are unsure about cables close to your mounting location.
???When installing your antenna, do not use a metal ladder. Do dress properly - shoes with rubber soles and heels, rubber gloves, and a long sleeved shirt or jacket.
???If an accident or emergency occurs with the power lines, call for qualified emergency help immediately.
Installation Instructions
The following sections contain procedures for installing the antenna on a suspended ceiling.
Suspended Ceilings With Flush Mounted Tiles
The antenna is configured to mount to a suspended ceiling track with flush mounted tiles. No modifications are necessary. After you have selected a suitable location, follow these steps to mount your antenna. It may be helpful to examine the illustration below before you install the antennas.

Step 1 Remove the two ceiling tiles on either side of the ceiling track.
Step 2 Line up the antenna???s mounting clips with the track.
Step 3 Grasp the antenna with one hand and the track with the other while gently pushing the antenna until the clips are securely attached to the track.
Step 4 Route the antenna cables into the space above the ceiling grid and connect them to the device or extender cables.
Step 5 Replace the ceiling tiles.
Note You may have to trim some material from one of the tiles to accommodate the antenna cables.
Suspended Ceilings With Recessed Tiles
The antenna can be mounted to a suspended ceiling with recessed tiles by using the provided plastic recessed ceiling mounting clip adapter. After you have selected a suitable location, follow these steps to mount your antenna.
Step 1 Remove two ceiling tiles on either side of the ceiling track.
Step 2 Mark a center point on the ceiling track at the location where you intend to mount the antenna.
Step 3 Mark a point 2 in. (6.3 cm) from either side of the center point. The distance between these two points should be 5 in. (12.7 cm).
Step 4 Examine the adapter clips. One side has an elongated opening and a tab.
Step 5 Follow these steps to install a recessed ceiling mounting clip adapter at each point:
a.Insert the side without the opening and tab onto the ceiling track.
b.Push the tab to lock the other end onto the ceiling track.
