## **Specification** 

Part No. : **WSA.2458.A.101151** 

Product Name : Phoenix WSA.2458 Dual Band Wi-Fi I-Bar 2.4/5.8GHz Antenna with 1M RG-174 RP-SMA(M) Feature : Wi-Fi/WLAN Adhesive Mount Antenna 1m RG-174 cable with RP-SMA(M) connector Low Profile for Ease of Installation Fully Customizable Cable and Connector 105*30*7.7mm RoHS compliant 

SPE-16-8-077/A      Page 1 of 29 

## **1. Introduction** 

The Phoenix WSA.2458 I-Bar antenna is a robust and low profile, dipole antenna operating on both the 2.4/5.8GHz bands for Wi-Fi applications. 

The Phoenix has a slim-line design, which allows for covert and convenient installation in any application, while its omnidirectional radiation pattern and 2.1dBi gain ensure constant reception and transmission. It is manufactured and tested in a TS16949 first tier automotive approved facility and has undergone full PPAP design, reliability and quality audits. 

The Phoenix is especially suited for applications such as first-tier automotive applications, aftermarket and telematics. 

The Phoenix has exceptional industry performance characteristics considering its very low profile (just 7.7mm) and compact size (105*30mm). 

This UV resistant antenna is designed to be mounted on glass or plastic but should not be mounted on a metal base. It comes with strong 3M double-sided adhesive for a permanent and secure fix to your application. 

Cable lengths, types and connectors are fully customizable.
