## Overview

The YEGT003W1AM is a high-performance GNSS terminal mount external dipole antenna designed for precision navigation and positioning applications. Operating in the 1559–1606 MHz frequency band, it supports GPS L1, GLONASS G1, Galileo E1, and BDS B1I/B1C systems, making it ideal for automotive, industrial tracking, IoT, and telematics solutions where reliable signal reception is critical.

**Key features:**

- Exceptional efficiency: Achieves up to 57.3 % efficiency in free-space conditions, ensuring robust signal capture even in challenging environments.
- Compact and lightweight: With dimensions of Φ 9 mm x 54.9 mm and a weight of just 5.1 grams, it is engineered for seamless integration into space-constrained devices.
- Omni-directional radiation: Linear polarization and an omni-directional radiation pattern provide consistent performance across diverse orientations.
- Flexible connectivity: Compatible with SMA male connector, offering versatility for various installation scenarios.
- Durable design: Constructed from TPE materials, it operates reliably in temperatures ranging from -40°C to +85°C and complies with RoHS and REACH standards.

**Performance highlights:**

- Low VSWR and high return loss minimize signal reflection, optimizing power transfer.
- High peak gain ensures strong signal reception, while tested radiation patterns confirm stability in both free-space and on-EVB conditions (straight or bent configurations).

**Applications:**

Ideal for portable GNSS devices, the YEGT003W1AM combines precision, durability, and adaptability. Its modular packaging (up to 320 units per carton) streamlines logistics for large-scale deployments.
