2.4-GHz Cisco Aironet radio device that uses an RP-TNC connector.

Safety Precautions

Warning

In order to comply with FCC radio frequency (RF) exposure limits, antennas should be located at a
minimum of 7.9 inches (20 cm) or more from the body of all persons.

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 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.

5. When installing your antenna, remember:

Statement 332

a. Do not use a metal ladder.

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

c. Do 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 complete 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, don’t 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

General Installation Instructions for Mast-Mounted Antennas

The following instructions are common to most mast-mounted installations.

Step 1 Assemble your new antenna on the ground at the installation site.

Step 2 Attach the antenna to the mast and connect its coaxial cable while you are on the ground.

Step 3 If you lose control of the mast while raising it, make sure that it does not fall in the wrong direction. Use

a durable non-conductive rope secured at each 2-foot level as the mast is raised. Have an assistant tend
the rope, ready to pull the mast clear of any hazards (such as power lines) if it begins to fall.

Step 4 Use the mounting bracket and hardware provided with the antenna.

Step 5 If the installation will use guy wires:

a. Install guy anchor bolts.

b. Estimate the length of guy wire and cut it before raising the mast.

c. Attach guy wires to a mast using guy rings.

Step 6 Carefully connect the antenna and mast assembly to its mounting bracket and tighten the clamp bolts.

a. For a guyed installation, you must have at least one assistant to hold the mast upright while you

attach and tighten the guy wires to the anchor bolts.

Step 7 Attach the provided self-adhering DANGER label at eye level on the mast.

Step 8 Install ground rods to remove any static electricity buildup and connect a ground wire to the mast and

ground rod. Use ground rods designed for that purpose, not a spare piece of pipe.

Grounding the Antenna

Follow these steps to ground the antenna in accordance with national electrical code instructions.

Step 1 Use No. 10 AWG copper or No. 8 or larger copper-clad steel or bronze wire as ground wires for both

mast and lead-in. Securely clamp the wire to the bottom of the mast.

Step 2 Secure the lead-in wire to an antenna discharge unit and the mast ground wire to the building with

stand-off insulators spaced from 4 ft (1.2 m) to 8 ft (2.4 m) apart.

Step 3 Mount the antenna discharge unit as closely as possible to where the lead-in wire enters the building.

Step 4 Drill a hole in the building’s wall as closely as possible to the equipment to which you will connect the

lead-in cable.

Caution There may be wires in the wall. Make sure your drilling location is clear of any obstructions or other

hazards.

Step 5 Pull the cable through the hole and form a drip loop close to where it enters the building.

Step 6 Thoroughly waterproof the lead-in area.
