## **1.** Introduction 

The AA.171 MagmaX Low Axial Ratio Magma magnetic mount external GNSS antenna is ideal for robust, covert installations where durability and small size is paramount. It is used in telematics and M2M applications, for example in commercial vehicle installations for fleet management. 

Typical Applications Include: 

- Timing -       Precision Positioning for Robotics / Automotive 

- Telematics -       Autonomous Routing 

Standard cable and connector version is 3 meter RG174 and SMA(M). Cable length and connector type are customizable upon request. 

Using a unique specialist feed structure this antenna delivers best in class axial ratio across all GPS, GLONASS, Galileo and BeiDou bands. Low axial ratio improves accuracy of GNSS system location and leads to quicker lock times. A front-end SAW reduces out-band interference from any nearby wireless transmitters, helping prevent LNA compression and burnout. Manufactured in a dedicated TS16949 facility, PPAP and IMDS documentation are available on request. Low power consumption lengthens device battery life. Adhesive mount version is available on request. 

The cable and connector is fully customizable, contact your regional Taoglas customer support team for further information.
