Installation Guide for Cisco Omnidirectional Antenna (AIR-ANT-SE-WiFI-O)

Cisco Aironet Omnidirectional Antenna (AIR-ANT-SE-WiFI-O)

---

This document describes the Cisco Aironet AIR-ANT-SE-WiFI-O Antenna and provides instructions for mounting it. The antenna operates in the 2.4-GHz and 5-GHz frequency bands and is designed for use with Cisco Spectrum Expert spectrum analyzer software. The antenna connects to the Cisco Spectrum Expert Sensor Wi-Fi card (hereafter referred to as the sensor card). The antenna’s omnidirectional qualities provide RF detection in all directions from the antenna. The antenna can be useful with all ISMS mobile features, but is especially useful in detecting and identifying RF devices
