Helix Antenna HX-HE202A

Overview

Harxon HX-HE202A embedded helix antenna is designed for high-precision positioning and offers superior satellite signal tracking, including GPS L1/L5，GLONASS L1/L3，BDS B1I/B1C/B2a/B2b，Galileo E1/E5a/E5b, and L-Band. Its compact form factor and lightweight design make it well-suited for integration into UAVs. The antenna is ideal for a wide range of applications such as surveying and mapping, remote sensing, disaster monitoring, precision agriculture, public safety surveillance, etc.

Key Features

Small Form Factor, Lightweight, Designed for Integration

With a compact integrated design measuring just φ38.7 × 41.8 mm, ≤8g, HX-HE202A combines both antenna and circuitry in a single lightweight unit, which minimizes payload on lightweight devices such as UAVs, enhancing endurance and portability.

Advanced Patented D-QHA Technology

HX-HE202A antenna adopts patented D-QHA technology for stable performance of wide-angle circular polarization (WACP), which ensures exceptional low elevation satellite tracking while maintaining high gain and providing reliable signal tracking.

Strong Anti-interference Performance

HX-HE202A optimizes circuit layout and equips a robust pre-filtered LNA that features an excellent out-of-band interference rejection performance and restraints possible unwanted electromagnetic interference.

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—providing high-precision and reliable positioning data.
