Introduction

Harxon HX-SE406A is a high-performance, full-frequency GNSS antenna designed for robotic lawn mowers, delivering centimeter-level positioning accuracy at an affordable price. With high gain (peak 5dBi), stable phase center, and multi-constellation full-frequency support, it ensures reliable navigation in challenging mowing terrains. Its compact design and good electromagnetic compatibility simplify integration, while stable signal tracking performance and robust multipath rejection guarantee consistent performance, making it the ideal choice for precision-driven, cost-effective lawn care solutions.

Key Features

High Phase Center Stability

HX-SE406A offers full support for superior satellite signals tracking, including GPS, GLONASS, Galileo, BeiDou, delivering a peak gain of 5 dBi, wide beamwidth, and exceptional wide-angle circular polarization (WACP).
Strong Anti-Interference Performance

The HX-SE406A’s advanced Low Noise Amplifier (LNA) enhances GNSS signal integrity with superior amplification, exceptional out-of-band rejection, and robust noise suppression.
Compact and Reliable Antenna Structure

HX-SE406A has a compact Φ120×15.8 mm form factor and lightweight 100g design, using proprietary microwave materials and precision molding for low loss and enhanced structural stability.
