## Overview

The YFGN001H3AM is a high-performance multi-band active GNSS antenna designed for professional applications requiring ultra-precise positioning across GPS (L1/L2/L5), BDS (B1/B2/B3), GLONASS (G1/G2/G3), Galileo (E1/E5a/E5b/E6), and L-Band frequencies (1164–1300MHz, 1525–1606MHz). Combining exceptional signal sensitivity with rugged durability, this antenna is engineered for mission-critical deployments in autonomous systems, geodetic surveying, and high-accuracy navigation.

Key features:
- Multi-GNSS support: Covers all major global navigation systems, including BDS-3 (B1C) and QZSS to ensure compatibility worldwide.
- High-gain LNA: Delivers 40 ±4 dB gain with a low noise figure (≤2.5dB), ideal for weak-signal environments like urban canyons or dense foliage.
- Superior RF performance: Features RHCP polarization, directional radiation pattern, and outstanding peak gain (up to 5.6dBi) for reliable signal acquisition.
- Robust design: Φ 122mm x 24.2mm housing with screw mounting, suitable for vehicular or fixed installations.
- Environmental resilience: Operates in -40°C to +85°C temperatures and complies with RoHS/REACH standards.

Technical highlights:
- Low VSWR and high efficiency minimize signal loss.
- Low axial ratio ensures consistent circular polarization for precision applications.
- 3D radiation pattern optimization for stable performance across elevations.

Target applications:
- Autonomous vehicles: Provides centimeter-level accuracy for ADAS and navigation.
- Geodetic surveying: Supports RTK/PPK systems with multi-frequency compatibility.
- Maritime: Ensures reliable positioning for vessels with L-band support.
- Military/defense: Resilient performance in harsh environments.
- Telematics and fleet management: Enables real-time tracking for logistics and heavy equipment.
