The Harxon X-Survey™ OEM antenna HX-CSX137A is a high-precision survey antenna that provides multi-constellation and multi-frequency signal reception. It is highly integrated and features dual 4G antennas, Wi-Fi and Bluetooth antennas in a compact package. This versatile antenna is ideal for geodetic surveys, oceanographic exploration, geological surveys, disaster monitoring and smart port operations.

Stable phase center for remarkable performance

The HX-CSX137A offers full support for reliable satellite signal tracking, including GPS, GLONASS, Galileo, BeiDou and L-band correction services. Multipoint injection technology keeps the phase center stable, ensuring millimeter positioning accuracy by minimizing the deviation between the phase center and geometric center.

Wide compatibility for solid reliability

This compact design combines GNSS, 4G, Wi-Fi and Bluetooth antennas, ensuring compatibility with RTK applications. The antenna layout provides excellent isolation between the embedded antennas, ensuring minimal interference.

tracking in complex environments

The antenna offers high gain performance with extremely low signal loss, enabling reliable satellite signal tracking. The wide beamwidth ensures robust signal availability in complex environments with obstacles such as treetops and buildings.

Strong immunity to interference

The advanced Low Noise Amplifier (LNA) improves signal filtering and out-of-band interference rejection, reducing electromagnetic interference and multipath effects across all GNSS frequency bands. This ensures consistent and reliable GNSS signals, even in environments with high levels of electromagnetic interference.

Compact design with low consumption

The antenna's integrated design minimizes power consumption, weight and dimensions while maintaining accuracy and reliability. With a diameter of only 111 mm, it is an ideal solution for precision applications.
