Introduction

The Harxon HX-CUX618A is a compact, multi-frequency GNSS helix antenna with integrated Wi-Fi and Bluetooth antennas for positioning and wireless connectivity. It supports GPS, GLONASS, Galileo, and BeiDou signals, as well as L-band correction services. Measuring Φ43.6 × 40.8 mm and weighing no more than 30 g, it is designed for integration into UAVs, surveying equipment, and personnel and vehicle monitoring devices. Harxon’s patented D-QHA technology and multi-point feeding design provide stable phase center performance, while a pre-filtered low-noise amplifier helps suppress out-of-band interference. Its integrated antenna design simplifies device development and supports wireless connection and configuration through mobile devices.

Key Features

Advanced D-QHA Technology for Consistent Performance

The HX-CUX618A combines patented D-QHA technology with multi-point feeding to maintain a stable phase center. A GNSS antenna gain of up to 2.8 dBi and a wide beam support reliable low-elevation satellite tracking for high-precision positioning in challenging environments.
Strong Anti-interference Performance

An optimized circuit layout and pre-filtered low-noise amplifier help the HX-CUX618A suppress out-of-band interference. This design limits unwanted electromagnetic signals and supports reliable GNSS reception when integrated into UAVs, surveying equipment, and monitoring devices.
Small Form Factor, Light Weight, Designed for Integration

Measuring Φ43.6 × 40.8 mm and weighing no more than 30 g, the HX-CUX618A fits easily into UAVs, surveying equipment, and monitoring devices. Its compact dimensions and lightweight construction help meet space and payload requirements without adding unnecessary bulk.
All-in-one Helix Antenna, Integrated with WIFI&BT Antenna

The HX-CUX618A combines GNSS positioning and Wi-Fi/Bluetooth antennas in a compact design. The integrated Wi-Fi/Bluetooth antenna provides a typical gain of 1 dBi, supporting mobile device connection and configuration while simplifying antenna integration and reducing development costs.
