Harxon HX-CA7603A GNSS Aviation Antenna


GPS L1/L2/L5 + GLONASS L1/L2/L3 + BeiDou B1/B2/B3 with 36dB Gain



The HX-CA7603A GNSS aviation antenna features a multi-point feeding design to achieve greater phase center stability. It effectively improves measurement accuracy and provides more accurate positioning.

The antenna’s LNA features an excellent out-of-band rejection performance, which can suppress the electro magnetic interference, providing stable and reliable GNSS signals. It effectively avoids disruptions when receivers are being interfered by wireless communication systems, for example power grid, communication base station or radio modem applications.

The dimension of HX-CA7603A is only 90 mm x 27.5 mm (without connector) with a light weight of only 150 grams, making it well suited for unmanned vessels or similar applications where high precision is needed. The IP67 ruggedized cover can protect the antenna from dust and water for high performance in harsh enironments.


  • Supports GPS, GLONASS and BeiDou
  • Stable phase center guarantees the accuracy of positioning within millimeter-level
  • Strong anti-interference ability
  • Small form factor meets IP67 standards
