Helix Antenna HX-HE205A

Overview

Harxon HX-HE205A embedded helix antenna is designed for high-precision positioning and offers superior satellite signal tracking, including GPS L1/L2, BDS B1I/B2I, GLONASS G1/G2/G3, Galileo E1/ E5b, QZSS L1/L 2 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 × 39.4 mm, HX-HE205A 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-HE205A 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-HE205A 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.
