Overview

The ANN-MB1-00 is a high-performance, multi-band active GNSS antenna designed for L1 and L5 frequency bands. It features an integrated Low Noise Amplifier (LNA) with a 5-meter cable and a magnetic base, providing reliable reception for GPS, GLONASS, Galileo, and BeiDou constellations. The module is housed in an IP67-rated enclosure and supports both magnetic and screw-mount installation for flexible deployment.

Why Choose This Part

The multi-band design significantly reduces convergence time for high-precision GNSS engines compared to single-band antennas. Its versatile mounting options, including a magnetic base and M4 screw holes, allow for rapid prototyping and secure permanent installation.

Applications

High-Precision Positioning
Ideal for RTK applications and centimeter-level positioning where multi-band (L1/L5) reception is required to mitigate ionospheric errors.
Autonomous Vehicles
Used in ADAS and unmanned ground vehicles that require robust signal tracking in challenging environments.
Industrial Telematics
Suitable for fleet management and asset tracking systems that demand a rugged, waterproof external antenna.

Getting Started

Connect the SMA plug directly to the GNSS receiver's antenna input, ensuring the host device provides a 3V to 5V DC bias to power the internal LNA. Position the antenna with a clear view of the sky on a ground plane to maximize the 3.8dBic peak gain.
