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 vertically and mount it as high as possible.
Note This antenna must be mounted vertically in order to maximize its directional propagation characteristics. Mounting it horizontally may noticeably decrease the antenna’s range and overall performance.
•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.

Mounting Instructions for the Cisco Aironet 6.5 dBi Diversity Patch Wall Mount Antenna
Installation Notes
•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.
–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 2-GHz cordless phones. These products can cause signal interference because they operate in the same frequency range as the device your antenna is connected to.
•Install the antenna in a vertical orientation to maximize signal propagation.
Installation Notes
You can mount the antenna using the mounting kit provided. The kit contains the following parts:
•Four #8 plastic wall anchors
•Four #8 x 3/4 in (1.9 cm) Philips™ type A pan head screws
Tools and Equipment Required
To install the antenna, you will need the following tools and equipment.
•A Philips™ screwdriver
•A portable hand or electric drill
•A 3/16 in (4.7 mm) drill bit
•A carpenter’s hammer
•A pencil
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.
