With its compact, lightweight, and robust design, the HX-HE401A combines superior RF performance with high reliability. It is easily integrated into lightweight UAVs and is compatible with a wide range of GNSS receivers. Typical applications include surveying and mapping, aerial surveying, navigation, remote sensing, disaster monitoring, traffic patrol, fleet management, public safety, etc.
Key Features
Consistent Performance across Full Frequency Bands
HE401A offers full support for superior satellite signals tracking, including GPS, GLONASS, Galileo, BeiDou, QZSS, and L-band, providing UAVs with reliable positioning in complex flight environments.
High Phase Center Stability and Consistent Performance
HE401A features a multi-point feeding technology that ensures a high phase center stability with centimeter level accuracy. It has a high peak gain and excellent axial ratios, enabling excellent multipath mitigation and a very precise phase center.
Small Form Factor, Light Weight, Designed for Integration
Weighting only 10g, the lightweight HE401A embedded antenna has a compact dimension, withФ45*H39.8mm only, making it ideal to be integrated into UAVs.
Tracking in Challenging Environments
The antenna delivers high gain and a wide radiation beam, enabling excellent reception of low-elevation satellite signals. It effectively tracks visible satellites even in challenging environments—such as under tree canopies or near buildings
