System Requirements

This antenna is designed for use with Cisco Aironet access points and bridges but can be used with any 5-GHz Cisco Aironet radio device that utilizes reverse polarity Neil Councilman (RP-TNC) connectors.

Installation Guidelines

Because the antenna transmits and receives 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. One way to do this is to orient the antenna horizontally and mount it as high as possible.

Keep the antenna away from metal obstructions such as heating and air-conditioning ducts, large ceiling trusses, building superstructures, and major power cabling runs. If necessary, use a rigid conduit to lower the antenna away from these obstructions.

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 pre-cast concrete walls limit signal penetration to one or two walls without degrading coverage.

Wood and concrete 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.

Safety Instructions

Follow these safety precautions 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 lines 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 intended mounting location.

If an accident or emergency occurs with the power lines, call for qualified emergency help immediately.

When installing your antenna in any location, do not use a metal ladder. Do dress properly - shoes with rubber soles and heels, rubber gloves, and a long sleeved shirt or jacket. When drilling mounting holes, wear safety glasses.

Installing the Antenna

The antenna ships with a mounting bracket and the hardware required to install the antenna on a suspended ceiling. Two mounting methods are available. You can mount the antenna using standard suspended ceiling T-rail clips or you can mount the antenna using the clips attached to the antenna mounting bracket. Figure 1 shows the layout of the detachable mounting bracket configured to use the suspended ceiling T-rail clips.

Tools and Equipment Required

To install the antenna, you will need the following tools and equipment.

The mounting kit supplied with your antenna consisting of:

Mounting bracket

Two T-rail clips with studs

Two plastic spacers

Two 1/4-20 T-rail nuts with built-in washers

A 9 mm open end wrench or suitable pliers

Standard screwdriver

A 3/4 in. (20 mm) drill bit

A Drill

A pencil or suitable marker

Installing the Antenna Using T-Rail Clips

Follow these steps to install the antenna using the T-rail clips. It may be helpful to refer to before you begin.


Step 1 Choose a location in which to install the antenna.

Step 2 Remove the adjacent ceiling panels on each side of the T-rail on which the antenna is to be installed.


Note The panels must be removed so you can attach the antenna's cables to the cables coming from the device using the antenna. Removing the pane lets you support to the ceiling T-rail when you snap the antenna in place on the mounting bracket.


Step 3 Attach the T-rail clips to the ceiling T-rail.

Step 4 Verify that the distance between the t-rail studs is 3.125-in (80 mm).

Step 5 Use a screwdriver to tighten the T-rail clip stud to the T-rail.

Step 6 Slip a plastic spacer onto the stud of each T-rail clip. Make sure the spacer legs are positioned against the T-rail. See Figure 1 for details.

Step 7 Position the mounting bracket into the T-rail clip studs.

Step 8 Start a T-rail nut on each stud.

Step 9 Tighten each T-rail nut wrench tight.

Step 10 Use the mounting bracket to determine and mark where to drill the antenna cable access hole in the ceiling panel.

Step 11 Drill a 3/4 in. (20 mm) hole at each mark.

Step 12 Position the antenna over the mounting bracket and feed each cable through its respective access hole.

Step 13 Grasp the ceiling T-rail as closely as possible to the mounting bracket while aligning the antenna with the retaining tabs.

Step 14 Snap the antenna over the retaining tabs.

Step 15 Connect the antenna cables.

Step 16 Replace the ceiling panels.

Installing the Antenna Using Attached Mounting Clips

Follow these steps to install the antenna on a suspended ceiling using the mounting clips attached to the antenna mounting bracket.


Note You cannot mount the antenna on suspended ceiling having recessed tiles. The clips are designed to be used on a ceiling having flush mounted tiles.



Step 1 If the T-rail clips are fastened to the antenna mounting bracket, remove them.

Step 2 Choose a location in which to install the antenna.

Step 3 Remove the adjacent ceiling panels on each side of the T-rail on which the antenna is to be installed.


Note The panels must be removed so you can attach the antenna's cables to the cables coming from the device using the antenna. Removing the pane lets you support to the ceiling T-rail when you snap the antenna in place on the mounting bracket.


Step 4 Snap the antenna over the retaining tabs on the mounting bracket

Step 5 Align the mounting clips with the edge of the ceiling T-rail where you want to mount the antenna.

Step 6 Grasp the ceiling T-rail as closely as possible to the mounting bracket while pushing the clips securely onto the rail.

Step 7 Connect the antenna cables.

Step 8 Replace the ceiling panels.

Suggested Cable

Cisco recommends a high-quality, low-loss cable for use with the antenna.


Note Coaxial cable loses efficiency as the frequency increases, resulting in signal loss. The cable should be kept as short as possible because cable length also determines the amount of signal loss (the longer the run, the greater the loss).


The antenna terminates with a RP-TNC plug after a short, 3-ft (0.91-m) cable. The mating connector to the antenna is an appropriate RP-TNC jack.
