Overview

Cisco Aironet High Gain Omnidirectional Ceiling
Mount Antenna (AIR-ANT1728)

This document outlines the specifications, describes the high gain omnidirectional ceiling mount
antenna, and provides instructions for mounting it on a suspended ceiling track. Designed for WLAN
applications operating in the 2.4- to 2.5-GHz frequency range, the antenna has a nominal gain of 5.2 dBi.
The antenna is used primarily with access points, but is compatible with Cisco Aironet radio products
utilizing a reverse-polarity threaded Neil Concelman (RP-TNC) connector.

This antenna is designed for use with Cisco Aironet access points, but can be used with any 2.4-GHz
Cisco Aironet radio device that utilizes a RP-TNC connector.

Installation Notes

Choosing a Mounting Location

The location of the antenna is important. Objects such as metal columns, walls, etc. will reduce
efficiency. Best performance is achieved when transmit and receive 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 attach to and hang from a standard suspended ceiling track having a width
from 13/16 inches (20.6 millimeters) to 1 1/4 inches (31.7 millimeters).

Tools and Equipment Required

To install the antenna on a suspended ceiling track, you will need the following tools and equipment.

• A ceiling track bracket (shipped with your antenna)

• A 7/16 inch (11.1 millimeters) wrench

• Cable ties or electrical tape

The following sections contain procedures for installing the antenna to a suspended ceiling track.
