Table 2 lists the minimum required attenuation between the access point radio and the antenna when using the lowest RF power setting. Using a higher RF power setting will require additional attenuation (for a given antenna).

The attenuation can be in the form of an attenuator, coax cable loss, or both. This attenuation is required for the system to meet the regulatory requirements of the indicated country. Failure to install the minimum amount of attenuation shown results in non-compliant operation. Table 2 shows the required attenuation in dB.

Note: X indicates that the antenna is not authorized for use in that country.

System Requirements

This antenna is designed for use with Cisco Aironet access points and bridges but can be used with any Cisco Aironet radio device that uses an N-connector.

Safety Precautions

Warning: Installation of this antenna near power lines is dangerous. For your safety, follow the installation directions.

Each year hundreds of people are killed or injured when attempting to install an antenna. In many of these cases, the victim was aware of the danger of electrocution but did not take adequate steps to avoid the hazard.

For your safety, and to help you achieve a good installation, please read and follow these safety precautions. They may save your life!

1. If you are installing an antenna for the first time, for your own safety as well as others, seek professional assistance. Your Cisco sales representative can explain which mounting method to use for the size and type antenna you are about to install.

2. Select your installation site with safety, as well as performance in mind. Remember: electric power lines and phone lines look alike. For your safety, assume that any overhead line can kill you.

3. Call your electric power company. Tell them your plans and ask them to come look at your proposed installation. This is a small inconvenience considering your life is at stake.

4. Plan your installation carefully and completely before you begin. Successful raising of a mast or tower is largely a matter of coordination. Each person should be assigned a specific task, and should know what to do and when to do it. One person should be in charge of the operation to issue instructions and watch for signs of trouble.

5. When installing your antenna, remember:

a. Do not use a metal ladder.

b. Do not work on a wet or windy day.

c. Dress properly—shoes with rubber soles and heels, rubber gloves, long sleeved shirt or jacket.

6. If the assembly starts to drop, get away from it and let it fall. Remember, the antenna, mast, cable, and metal guy wires are all excellent conductors of electrical current. Even the slightest touch of any of these parts to a power line completes an electrical path through the antenna and the installer: You!

7. If any part of the antenna system should come in contact with a power line, do not touch it or try to remove it yourself. Call your local power company. They will remove it safely.

8. If an accident should occur with the power lines call for qualified emergency help immediately.

Installation Notes

The antenna is designed to mount on a dedicated mounting panel on the access point. No special tools are required.

The antenna is resistant to the full range of outdoor environments. Therefore, Cisco does not recommend using cable or antenna waterproofing materials. Using such materials may cause important drainage holes to be blocked. The antenna base has four drain holes.

There are also drain holes located under the cap at the top of the antenna. These holes allow proper drainage if the antenna is deployed with the cap pointing towards the ground.

Note: Ensure that the cap is not damaged.

Figure 1 shows the location of the drain holes in both the antenna base and under the antenna cap.

Mounting the Antenna

To mount the antenna on the access point, position the antenna below the antenna connector on the access point and thread it hand tight, as shown in Figure 2.

The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.

The following information is for FCC compliance of Class B devices: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If the equipment causes interference to radio or television reception, which can be determined by turning the equipment off and on, users are encouraged to try to correct the interference by using one or more of the following measures:

■Reorient or relocate the receiving antenna.

■Increase the separation between the equipment and receiver.

■Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

■Consult the dealer or an experienced radio/TV technician for help.

Modifications to this product not authorized by Cisco could void the FCC approval and negate your authority to operate the product.
