D-Helix Antenna HX-CUX038A

Overview

HX-CUX038A is a multi-functional embedded helix antenna that integrates GNSS and 4G into a single compact design, simplifying UAV system integration. It supports full-band signal reception including BDS B1/B2/B3, GPS L1/L2/L5, GLONASS L1/L2/L3, Galileo E1/E5a/E5b/E6, and L-Band, while also covering 4G frequency bands. With its highly integrated design, the antenna is ideal for seamless integration into lightweight UAVs, handheld devices, and other portable platforms. Typical applications include surveying and mapping, aerial surveying, navigation, remote sensing, disaster monitoring, traffic patrol, fleet management, public safety, etc.

Key Features

Multifunctional Antenna Integrated with 4G Antenna

HX- CUX038A offers full support for superior satellite signals tracking, including GPS, GLONASS, Galileo, BeiDou, and L-band.Besides, the antenna supports 4G connectivity with an integrated GNSS + 4G design.

Small Form Factor, Lightweight, Designed for Integration

HX-CUX038A features a compact design measuring only φ44*73.9mm, and weights only 15g. The antenna features a lightweight design with integrated GNSS and 4G compatibility, simplifying integration process.

High Phase Center Stability and Consistent Performance

The antenna features a multi-point feeding technology that ensures a high phase center stability with centimeter level accuracy. It has a high peak gain of 2.5 dBi and excellent axial ratios.

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.
