ARKNAV GPS Tracking System

100% Real-time Visibility with Zero Blind Spots

AR-4 GPS and GSM Dual Antenna

For GPS tracking systems, M2M solutions and telemetry applications

Introduction

A GPS device is only as good as the antenna it uses. A bad quality antenna might compromise the whole GPS tracking or navigation system, and compared to the effort and cost you might spend uninstalling and repairing the system - buying a good quality GPS antenna is really a no-brainer!

AR-4 is a low profile combine antenna for telemetry, fleet management, GPS tracking and M2M applications. Its GPS antenna has unique 10 watt RF protection, 3 signal noise filters and 2-stage LNA (Low Noise Amplifier) design, which provides the most accurate signal to GPS devices. Just like all the other ARKNAV antennas, AR-4 is made with high quality double-shielding cable and silver coated conducting pin, and under RoHS directive.

So, save your company reputation and choose the right antenna. We’ve been in the business for many years, and the low failure rate of our antennas has been proven by our regular customers all over the world. All our antennas are made and tested in our own factory in Taiwan to very strict quality control standards. You are welcome to send your inquiries to us, and we are more than happy to offer a free testing sample to prove our antenna’s performance and quality.
