Cisco Catalyst 2.4 GHz and 5/6 GHz

Dual-Band Polarization-Diverse Directional

Patch Antenna (C-ANT9103=)

First Published: March 13, 2020

Last Updated: April 17, 2020

This document describes the Cisco Catalyst 2.4 GHz and 5/6 GHz Dual-Band Polarization-Diverse

Directional Patch Antenna (C-ANT9103=), and provides electrical specifications and mounting

instructions.

The antenna is an octal DART port polarization-diverse patch antenna that operates over the 2.4 GHz

band and extended 5 GHz band (up to 7.125 GHz), and IoT. It has 8 RF paths and 16 digital lines. It also

has an LED. The antenna ships with an articulating mount for use on flat surfaces and masts, and is

adjustable in both horizontal and vertical planes.

The antenna is designed for use in indoor and outdoor environments with an approved Cisco Catalyst

series access point that requires four dual-band and four 5/6 GHz antennas. The antenna also includes

circuitry to enable self-identification of the antenna by the Cisco Catalyst Series access points.

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, read and follow these safety precautions. They may save your

life!

If you are installing an antenna for the first time, for your own safety as well as that of others, seek professional

assistance. Your Cisco sales representative can explain which mounting method to use for the size and type of

antenna you are about to install.

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.

Call your electric power company. Tell them your plans and ask them to come and look at your proposed installation.

This is a small inconvenience considering your life is at stake.

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.

When installing your antenna, remember:

—Do not use a metal ladder.

—Do not work on a wet or windy day.

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

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!

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.

If an accident occurs with the power lines, call for qualified emergency help immediately.

Installation Notes

Antennas transmit and receive radio signals that are susceptible to RF obstructions and common sources of interference

that can reduce throughput and the range of the device to which they are connected. Follow these guidelines to ensure

the best possible performance:

Install the antenna vertically and mount it with the cables pointing towards the ground.

Keep the antenna away from metal obstructions such as heating and air-conditioning ducts, large ceiling trusses,

building superstructures, and major power cabling runs. If necessary, use a rigid conduit to lower the antenna away

from these obstructions.

In an outdoor environment, connect the antenna to a lightning arrestor and ensure proper grounding.

The density of the materials used in a building’s construction determines the number of walls the signal can pass

through and still maintain adequate signal strength. Consider the following before choosing the location for your

antenna:

—Signals penetrate paper and vinyl walls with little change to signal strength.

—Signals penetrate only one or two solid and precast concrete walls without degrading signal strength.

—Signals penetrate three or four concrete and wood block walls without degrading signal strength.

—Signals penetrate five or six walls constructed of drywall or wood without degrading signal strength.

—Signals are likely to reflect off a thick metal wall and may not penetrate it at all.

—Signals are likely to reflect off a chain link fence or wire mesh spaced between 1 and 1 1/2 inch. (2.5 and 3.8

cm). The fence acts as a harmonic reflector that blocks the signal.

Install the antenna away from microwave ovens and 2 GHz cordless phones. These products can cause signal

interference because they operate in the same frequency range as the device to which your antenna is connected.
