Mini choke ring antenna HX-CGX611A

The Harxon HX-CGX611A is a high performance GNSS antenna for base stations that provides full support for tracking satellite signals including GPS, GLONASS, Galileo, BeiDou, QZSS, IRNSS, SBAS and L-band correction services. This mini choke ring antenna is designed for applications that require absolute positioning accuracy and multipath rejection, such as land and marine surveying, earthquake and landslide monitoring, deformation monitoring and container operations at port facilities.

High phase center stability

The HX-CGX611A features a unique choke ring design that provides excellent multipath rejection for stable satellite signal tracking. Harxon's patented multi-point injection technology ensures phase center repeatability and minimizes measurement drift, achieving sub-millimeter stability that is ideal for mission-critical applications.

Excellent signal tracking in difficult environments

With high gain and wide beamwidth, the HX-CGX611A delivers reliable satellite signal reception even at low elevations. It quickly tracks available satellites in obstructed environments and ensures stable GNSS signals.

Strong immunity to interference

The antenna's LNA provides excellent out-of-band interference rejection, suppressing electromagnetic interference from power grids, communication base stations or radio modems. This reduces the risk of signal loss and increases the reliability of GNSS signals.

Mini design with robustness and durability

The HX-CGX611A is housed in a robust IP67-certified housing that is protected against dust, rain and sunlight. With a mean operating time (MTBF) of over 30,000 hours, it works reliably even under extreme conditions such as high humidity, salt mist and temperature fluctuations. Its compact size makes it easy to integrate into positioning solutions.
