Installation Notes - Cisco 4G-ANTM-OM-CM Manual

Cisco Aironet Dual-Band Omni-Directional Antenna (AIR-ANT2547V-N, AIR-ANT2547V-N-HZ, and ANT2547VG-N)
For your safety, read and follow these safety precautions.
1. Before you install an antenna, contact your Cisco account representative to explain which mounting method to use for the
size and type of antenna that you are about to install.
2. Find someone to help you—installing an antenna is often a two-person job.
3. Select your installation site with safety, as well as performance, in mind. Remember that electric power lines and phone
lines look alike. For your safety, assume that any overhead line can kill you.
4. Contact your electric power company. Tell them your plans and ask them to come look at your proposed installation.
5. Plan your installation carefully and completely before you begin. Each person involved in an installation should be assigned
to 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.
6. When installing your antenna, follow these guidelines:
a. Do not use a metal ladder.
b. Do not work on a wet or windy day.
c. Dress properly: wear shoes with rubber soles and heels, rubber gloves, and a long-sleeved shirt or jacket.
7. If the assembly starts to drop, move away from it and let it fall. Because 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.
8. 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 to have it removed safely.
9. If an accident should occur with the power lines, call for qualified emergency help immediately.

Installation Notes

The antenna is designed to connect to a dedicated antenna port on the access point. No special tools are required to install the
antenna directly to the access point. The antenna can also be mounted on a mast. To mast mount the antenna, you must
purchase a suitable U-bolt bracket from a third party.
The antenna is resistant to the full range of outdoor environments. After the antenna is attached to the access point, seal the
connections to prevent moisture and other weathering elements from affecting performance. Cisco recommends using a coax
seal (such as CoaxSeal) for outdoor connections. Silicone sealant or electrical tape are not recommended for sealing outdoor
connections.
Choosing a Mounting Location
The antenna is designed to create an omni-directional broadcast pattern. To achieve this pattern, mount the access point clear
of obstructions to the sides of the radiating element. If the mounting location is on the side of a building or tower, the antenna
pattern is degraded by the building or tower side. Generally, the higher an antenna is above the ground, the better it performs.
Install your antenna about 5 to 10 foot (1.5 to 3 m) above the roof line and away from all power lines and obstructions.
Tools and Equipment Required
No tools are required to mount the antenna directly to the access point. However, you may need a ¾-in. (19-mm) open end or
combination wrench (or adjustable wrench) to remove the antenna port covers. To mast mount the antenna, you must purchase
the U-bolt bracket from a third party.
For information about tools required to mount the access point, see the appropriate access point documentation.
