SPE-24-8-134-A 

The Taoglas MagmaX2 AA.178.B is an external, IP67 rated, magnetic mount, high-performance multiband GNSS antenna. Utilizing an internal, active stacked patch, the GNSS antenna supports both L1 and L5 bands. It is an economical, after market solution for the highest accuracy centimeter-level tracking applications. 

Typical applications include: 

- UAVs and Robotics 

- Transportation and Autonomous Vehicles 

- Marine and Agriculture 

- Navigation 

This compact antenna exhibits excellent radiation patterns on both L1 and L5 bands and with a low noise figure to preserve signal quality, which helps minimize time to first fix. It also features excellent out-of-band rejection to prevent out-of-band signals from overdriving or damaging its LNAs. The AA.175 features very tight Phase Centre Offset (PSO) at just ±2cm at the L1 Band and ±5cm at the L2. The precision of antenna phase center directly affects the accuracy of GNSS positioning systems and can ensure that the accuracy of the receiver can really achieve cm-level accuracy. 

This antenna has been tuned and tested on a 70 x 70 mm ground plane, and has a 2 stage LNA ensuring good signal strength. It can operate with an input voltage ranging from 1.8 to 5 volts. 

The enclosure is made from robust ABS material and is IP67 rated to endure the most challenging of environments. It is supplied with 3m RG-164 cable and SMA(M) connector, both of which can be customized to suit your application. 

Contact your regional Taoglas customer support team to request these services or additional support to integrate and test this antenna’s performance in your device.
