Key Features

Advanced Patented D-QHA Technology

HX-CU7005A adopts Harxon patented D-QHA technology with wide-angle circular polarization (WACP), enabling exceptional low-elevation satellite tracking while maintaining high gain and reliable GNSS signal reception for stable positioning performance, even in challenging operating environments.
High Phase Center Stability and Consistent Performance

HX-CU7005A features multi-point feeding technology for high phase center stability and centimeter-level accuracy. High gain, ultralow signal loss, wide beamwidth and symmetric radiation patterns ensure reliable low-elevation satellite tracking and consistently accurate GNSS positioning performance.
Compact Design with Low Power Consumption

Weighing only 10 g and measuring just Φ30 × H34 mm, HX-CU7005A combines a compact, lightweight form factor with low power consumption for easy integration into UAV platforms, helping reduce payload, extend flight endurance and improve overall system reliability.
