## Overview

The YEGN000Q1A represents the pinnacle of rugged, high-performance GNSS antenna technology, designed to deliver multi-constellation, dual-band (L1/L5) positioning in the most demanding environments. Combining active amplification with industrial-grade durability, these antennas provide unmatched signal clarity and reliability for applications requiring centimeter-level accuracy. With IP67 ingress protection, and extended temperature operation (-40°C to +85°C), they are engineered to thrive in harsh outdoor, automotive, and industrial settings.

Key features and technical specifications:

- Dual-band precision and active amplification
- Frequency bands: 1164–1189MHz (L5) and 1559–1606MHz (L1), supporting GPS, Galileo, BDS, QZSS, and GLONASS.
- Integrated LNA: Delivers 17 ±3dB total gain (21 ±3 dB at PCBA) with an ultra-low noise figure (≤2.5dB), enhancing weak signal reception in urban canyons or remote areas.
- Advanced filtering: SAW filters and hybrid couplers provide 60dB out-of-band attenuation, minimizing interference from adjacent frequencies.

Superior RF performance:

- Peak Gain: 1.39dBi (max) with RHCP polarization for multipath rejection.

Industrial-grade durability:

- IP67 rating: Fully dustproof and waterproof, suitable for marine or outdoor deployments.
- UV-resistant and flame-retardant housing: Compliant with UL 94 V-0 and UL 746c f1 standards.

Mounting flexibility:

- YEGN000Q1A: Bracket-mounted with 0.7N·m torque support for permanent fixtures.

Power efficiency and compliance:

- Low power consumption: Operates at 3–5V, ideal for battery-powered systems.
- RoHS/REACH compliant: Environmentally safe for global deployments.

### Target applications

These antennas are ideal for mission-critical systems requiring high precision and reliability:

1. Autonomous vehicles: Lane-level navigation for ADAS and robotics.
2. Marine: Offshore navigation, and other positioning devices.
3. Precision agriculture: Guidance systems for tractors and harvesters.
4. Industrial IoT: Asset tracking in ports, mining, and logistics.
5. Surveying and geodesy: High-accuracy mapping and timing synchronization.
