3D choke ring antenna HX-CGX601A

The HX-CGX601A's unique 3D choke ring design ensures excellent multipath rejection across all GNSS frequency bands, including L-band. The antenna features Harxon's patented multi-point feed technology, which achieves high phase center stability and improves measurement accuracy. This makes it ideal for CORS stations, bridge and building deformation monitoring, and geological monitoring, thanks to its sub-millimeter phase center stability.

signal tracking in difficult environments

The HX-CGX601A's ability to receive low elevation signals with high zenith gain and wide beamwidth makes it an excellent choice for tracking visible satellites. It delivers stable and accurate GNSS data in complex environments such as tree lines or construction sites.

Strong immunity to interference

The antenna's LNA provides excellent out-of-band interference rejection, effectively suppressing electromagnetic interference (EMI). This ensures the stability and reliability of GNSS signals and prevents link interruptions caused by interference with wireless communication systems such as power grids or communication base stations.

Robust and durable

The HX-CGX601A is housed in a rugged glass fiber reinforced polymer (GFRP) enclosure for structural reliability. The choke rings are treated for increased durability in harsh environments. The IP67-rated enclosure protects the antenna from dust and water, and the mean time between failure (MTBF) exceeds 30,000 hours, ensuring long-term outdoor use in challenging conditions such as extreme temperatures, high humidity, and saline environments.
