• The Magma AA.174 a GNSS external antenna with low axial ratio. 
• It 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. 
• It comes with a 3 meter, standard RG174 cable and SMA(M) connector. 
• Using a unique feed structure this antenna delivers low axial ratio levels across all GPS, GLONASS, Galileo and BeiDou bands.
• Low axial ratio improves the accuracy of GNSS system location leading to quick lock times. 
• A front-end SAW reduces out-band interference from any nearby wireless transmitters, helping prevent LNA compression and burnout.
