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.
Contact your electric power company. Tell them your plans and ask them to come look at your proposed installation.
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.
When installing your antenna, follow these guidelines:
Do not use a metal ladder.
Do not work on a wet or windy day.
Do dress properly—wear shoes with rubber soles and heels, rubber gloves, and a long-sleeved shirt or jacket.
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.
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.
If an accident should occur with the power lines, call for qualified emergency help immediately.

Installation Location

Warning: Do not locate the outdoor antenna near overhead power lines or other electric light or power circuits, or where
it can come into contact with such circuits. When installing the antenna, take extreme care not to come into contact with
such circuits, as they may cause serious injury or death. For proper installation and grounding of the antenna, please refer
to national and local codes (for example, U.S.:NFPA 70, National Electrical Code, Article 810, Canada:Canadian Electrical
Code, Section 54). Statement 1052
The location of the antenna is important. Objects such as metal columns, walls, and so on, reduce efficiency. Best
performance is achieved when antennas are mounted at the same height and in a direct line of sight with no obstructions.
If this is not possible and reception is poor, you should try different mounting positions to optimize reception.
The antenna is designed to create an omnidirectional broadcast pattern. To achieve this pattern, the antenna should be
mounted clear of any obstructions to the sides of the radiating element. If the mounting location is on the side of a
building or on a tower, the antenna pattern is degraded on the building or tower side.
Antenna installation and replacement should only be performed at one of the following, certified location types:
Utility maintenance and repair depot
Cisco DF facility
