Introduction

Harxon HX-CH7018A embedded antenna is designed for high precision positioning and offers superior satellite signal tracking, including GPS, GLONASS, GALILEO, and Beidou as well as L-Band correction service. Its RTK level positioning accuracy makes it ideal to be integrated into application as surveying and mapping, and various UAVs operations.

Key Features

Advanced D-QHA Technology for Consistent Performance

HX-CH7018A features multi-point feeding technology that ensures high phase center stability. Meanwhile, adopting advanced patented D-QHA technology and covering a wider frequency band, HX-CH7018A achieves extraordinary 2.8dBi gain for reliable and consistent performance.
Strong Anti-interference Performance

HX-CH7018A optimizes circuit layout and equips robust pre-filtered LNA that features excellent out-of-band interference rejection performance and restraints possible unwanted electromagnetic interference.
Small Form Factor, Light Weight, Designed for Integration

Weighting only 8g, HX-CH7018A has a compact dimension of D44*H28mm only, making it ideal to be integrated into UAVs.
