## **1.** Introduction 

The Taoglas Magma AL100 is a high-performance active L-Band, external magnetic mount, SatCom antenna. Engineered with high gain and high efficiency on the L-Band (1525 to 1560MHz), it is used as an additional feed to provide data to correct, or augment, traditional GNSS signals. The L-band is leveraged as a low-cost alternative to traditional RTK services and is perfect for applications where there is limited or no terrestrial cellular connectivity and RTK is not an option. 

Typical applications include: 

- Fleet Management and Telematics 

- Asset Tracking and Navigation 

- Precision Agriculture 

- Autonomous Robotics 

This compact antenna exhibits excellent radiation patterns on L-Bands and with a low noise figure to preserve signal quality helps minimize time to first fix. It also features excellent out-of-band rejection to prevent outof-band signals from overdriving or damaging its LNAs. The AL100 has been tuned and tested on a 70x70 mm ground plane, working at GPS L-Band center frequency of 1542 MHz, with a 2 stage LNA ensuring good signal strength. It can operate with an input voltage ranging from 1.8 to 5 volts. 

For embedded application, the Taoglas ALPDF254 is an alternative active patch antenna supplied with cable and connector for easy integration into an IoT device. 

The cable length and connectors on the AL100 are fully customizable. 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.
