## Description

This high-performance, multi-band GNSS antenna is engineered for applications that require high accuracy and continuous operation. This antenna delivers robust and reliable performance, while simultaneously supporting GPS, GLONASS, BeiDou, and Galileo constellations across multiple frequency bands, as well as L-band correction services.

Engineered to outperform standard patch antennas, this antenna provides superior signal clarity and stability for professional use. It captures and amplifies satellite signals, delivering a clean, high-quality data stream to your GNSS module through an integrated 150mm coaxial cable with a standard IPEX (U.FL) connector.

- **Multi-Band & L-Band Support:** Full compatibility with GPS L1/L2, GLONASS L1/L2, BeiDou B1/B2/B3, Galileo E1/E5b, and L-band signals ensures maximum satellite availability and support for real-time correction services like PPP and u-blox PointPerfect.
- **High-Gain Signal Amplification:** A high passive gain of 5.5 dBi is paired with an integrated 40 dB low-noise amplifier (LNA) to ensure a strong and reliable satellite lock in obstructed environments, such as urban canyons or under foliage.
- **Survey-Grade Accuracy:** Achieves a highly stable phase center with an error of just ±2mm and maintains a low noise figure (=2 dB), making it ideal for applications requiring centimeter-level precision.

Housed in a secure 119.9mm enclosure, the BT-3710 is built for dependable field deployment. Its wide operating range of -40°C to +85°C ensures consistent performance in any environment.
