D-Helix™ Antenna HX-CU7005A

Overview

Harxon HX-CU7005A embedded helix antenna is designed for high precision positioning service and offers superior satellite signal tracking, including GPS, GLONASS, GALILEO, BeiDou, as well as L-Band correction service. Its centimeter level positioning accuracy makes it ideal to be integrated into applications as surveying and mapping, and various UAVs operations.

Key Features

Advanced Patented D-QHA Technology

HX-CU7005A 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.

High Phase Center Stability and Consistent Performance

HX-CU7005A features multi-point feeding technology that ensures high phase center stability with centimeter level accuracy. Its high gain with ultralow signal loss, wide beam width effectively improve positioning accuracy..

Compact Design with Low Power Consumption

Weighting only 10g, HX-CU7005A has a compact dimension of only D30*H34mm. It’s also a low power consumption antenna that could prolongs fly endurance of the UAVs..
