Cisco Aironet 8-dBi Omni-Directional Antenna (AIR-ANT2480V-N)

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 on page 148 shows the location of the drain holes in both the antenna base and under the antenna cap.
