Product Overview

The 3M N-J Connector GPS BDS Car Navigation Antenna is a high-performance active multi-constellation positioning antenna designed specifically for automotive navigation and precision tracking applications. Engineered to deliver reliable signal acquisition even in obstructed environments like urban canyons, tunnels, and remote mountainous areas, this antenna solves common issues of inaccurate positioning and dropped navigation signals that plague factory-installed and low-quality aftermarket antennas.

With 3 meters of high-purity copper shielded cable, it allows flexible placement for optimal signal reception, while supporting both GPS and Beidou (BDS) satellite constellations for consistently accurate positioning across diverse operating conditions. It is compatible with most aftermarket navigation systems, Android car stereos, and commercial vehicle tracking equipment.

Key Features

  • ✅ Dual Constellation Support: Compatible with both GPS (1575.42MHz) and BDS Beidou (1561.09MHz) for expanded satellite coverage and improved positioning accuracy

  • ✅ 3 Meter (9.8ft) Shielded Cable: High-purity pure copper core with aluminum foil shielding minimizes signal loss, enables flexible optimal antenna placement anywhere on the vehicle

  • ✅ High Gain Active Amplifier: Built-in low-noise amplifier boosts signal strength for reliable lock even in weak signal environments

  • ✅ Right-Handed Circular Polarization: Optimized for satellite signal reception with excellent interference rejection

  • ✅ Weather Resistant Design: Operates reliably across a wide temperature range and 100% humidity, suitable for all climate conditions

  • ✅ Multiple Connector Options: Available in N-J, SMA male, Fakra C, and TNC-F interfaces to fit most common navigation devices and head units

  • ✅ Easy Installation: Optional magnetic mounting base allows quick, secure installation without permanent modifications
