Introduction

Features of GPSL1L5 Antenna

The RAT-105 Multi-Band GNSS Active Antenna is engineered for reliable and high-precision satellite positioning across multiple global navigation systems, including GPS, BeiDou (BDS), and Galileo. Supporting L1/B1/E1 and L5/B2a/E5a frequency bands, it features a high-performance low-noise amplifier (LNA), RHCP polarization, excellent impedance matching, and low VSWR for superior signal reception in challenging environments. Its compact magnetic-mount design, low power consumption, and stable performance over a wide operating temperature range make it an ideal choice for demanding GNSS applications.

Typical Applications

The RAT-105 is widely used in high-precision GNSS positioning, RTK surveying systems, autonomous vehicles, precision agriculture, UAV navigation, fleet management, intelligent transportation systems (ITS), construction machinery, and IoT tracking devices. It is also suitable for industrial automation, timing synchronization, and other applications requiring stable multi-constellation GNSS signal reception and reliable positioning performance.
