Harxon HX-CUX012A Embedded GNSS Helix Antenna

GPS L1/L2/L5, GLONASS L1/L2/L3. Galileo E1/E5a/E5b/E6, BeiDou B1/B2/B3, QZSS L1/L2/L5/L6, IRNSS L5, SBAS L1/L5, L-Band



The Harxon HX-CUX012A embedded helix antenna is designed for high-precision positioning of UAV and offers superior satellite signal tracking, including GPS, GLONASS, GALILEO, Beidou, QZSS, SBAS, IRNSS as well as L-Band correction service. It provides excellent axial ratios, enables excellent multipath mitigation and a very precise phase center. As the helix antenna with the lowest profile ever, it is easy to be integrated, ideal for various UAV applications such as aerial photography, remote sensing, infrastructure inspection, traffic control and public security.

The HX-CUX012A antenna is designed with an extremely low profile (21.9 mm) and weighs only 8g with a compact dimension of ¢46*21.9mm, making it ideal to be integrated into UAVs, surveying and monitoring devices. It meets the strict demands of low profile.

The HX-CUX012A features a multi-point feeding technology that ensures a high phase center stability with centimeter level accuracy. It has a high peak gain of 3.3 dBi and excellent axial ratios, enabling excellent multipath mitigation and a very precise phase center.

The HX-CUX012A antenna features an optimized circuit layout and is equipped with a robust pre-filtered LNA that features an excellent out-of-band interference rejection performance and restraints possible unwanted electromagnetic interference.

The HX-CUX012A 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.


  • Low Profile for Easy Integration
