Harxon HX-CUX003A OEM GNSS Antenna


GPS L1/L2/L5 + GLONASS L1/L2/L3 + Galileo E1/E5a/E5b/E6 + BeiDou B1/B2/B3 + QZSS L1/L2/L5 + IRNSS L5 + SBAS L1/L5 + L-band with 36dB Gain



The HX-CUX003A OEM GNSS antenna from Harxon is a high gain, low profile and compact active antenna that provides reliable and consistent positioning services for high dynamic applications such as UAVs and precision agriculture. Its small form factor, lightweight design, high sensitivity and low power consumption makes it ideal to be integrated into UAVs that are applied to surveillance, infrastructure inspection, public security, remote sensing and precision agriculture.

The Harxon HX-CUX003A offers support for GPS, GLONASS, Galileo, BeiDou, QZSS, IRNSS and SBAS as well as L-Band correction services. It offers a very stable phase center variation with advanced multi-point feeding technology, exceptional low elevation satellite tracking with symmetric radiation patterns, high gain with ultra-low signal loss and outstanding wide-angle circular polarization (WACP) which ensures excellent positioning accuracy.

The HX-CUX003A antenna offers a robust pre-filtered LNA to minimize de-sensing from high level out-of-band signals and reduced electromagnetic interference for consistent and reliable GNSS signals.​


  • Comprehensive GNSS support: GPS, GLONASS, Galileo, BeiDou and QZSS, IRNSS, SBAS as well as L-Band correction services
  • Centimeter phase center repeatability
  • Improved signal filtering and excellent multipath rejection
  • Low profile, light weight design
