2D choke ring antenna HX-CG7601A

The HX-CG7601A's unique 2D choke ring design ensures excellent multipath rejection across multiple GNSS frequency bands, including GPS, BeiDou, GLONASS, Galileo, QZSS and SBAS. It features Harxon's patented multi-point injection technology, which ensures high stability of the phase center and effectively improves measurement accuracy, making it ideal for CORS stations, bridge and building deformation monitoring, and geological monitoring applications.

signal tracking in difficult environments

The HX-CG7601A features low elevation signal reception with high zenith gain and wide beamwidth, providing stable and accurate GNSS data even in difficult environments such as tree lines or construction sites.

Strong immunity to interference

The LNA of this antenna provides excellent out-of-band interference rejection, which effectively suppresses electromagnetic interference (EMI) and ensures the stability and reliability of GNSS signals. It prevents signal interruptions caused by interference from power grids, communication base stations or radio modems.

Robust and durable

The HX-CG7601A is housed in a rugged glass fiber reinforced polymer (GFRP) enclosure that can withstand dust, rain, splashes and sunlight. It meets the IP67 standard and operates reliably in harsh environments, including extreme temperatures, high humidity and salt mist.

Important functions

• Supports GPS, GLONASS, Galileo, BeiDou, QZSS and SBAS signals
• Stable phase center guarantees positioning accuracy in the sub-millimeter range
• High immunity to interference
• Robust, IP67-certified housing for use in extreme environments
