Overview
Key Features
Multi-System & Multi-Band Compatibility with Strong Anti-Interference
Adopts multi-arm and multi-feed point technology, supporting reception of L1/L2/L5 (GPS), L1/L2/L3 (GLONASS), B1/B2/B3 (BDS), E1/E5/E6 (Galileo), and L-band signals. Equipped with built-in pre-filters and low-noise amplifiers (LNA), it delivers excellent out-of-band suppression, ensuring stable operation in harsh electromagnetic environments—ideal for high-precision measurement scenarios like UAVs and micro RTK.
Optimized Quadrifilar Helix Antenna for Superior Signal Reception
Utilizes quadrifilar helix architecture to ensure right-hand circular polarization (RHCP) and stable phase center performance, minimizing measurement errors. With peak gain ≥3.0 dBi, small gain roll-off, and axial ratio ≤1.5dB @ zenith, it excels in receiving low-elevation satellite signals, enhancing positioning reliability across 360° azimuth coverage.
High-Performance LNA for Precise Signal Amplification
Features LNA with gain of 35±3.0dB, low noise figure (≤1.8dB @25°C with pre-filter), and output VSWR ≤1.8:1 (typ.), effectively amplifying weak signals while reducing interference. Compatible with 3.0~6.0V DC power supply (current ≤50mA), ensuring stable signal transmission for high-precision applications.
Compact, Lightweight & Rugged for Portable Scenarios
Weighs ≤38g with a space-saving design, easy to install via 3 bottom screws. IP67 waterproof rating, operating temperature -40℃~+85℃, and 95% non-condensing humidity resistance make it ideal for portable devices like sub-meter handhelds/tablets, ensuring durability in harsh environments.
