Harxon Introduces Two New GNSS Antennas at InterGeo Digital

By Sarah Simpson / 16 Oct 2020

HARXON has virtually announced the addition of one autonomous antenna HX-CVX603A and one mini choke ring HX-CGX611A to its autonomous and surveying applications respectively. The announcement was made during the InterGeo 2020 Digital EXPO, which ran from October 13th to 15th 2020.

Harxon Introduces Two New GNSS AntennasBy adopting a special fence structure for broadband and miniaturization, the HX-CVX603A weighing only 250g, is smaller by 40% in diameter than its predecessor HX-CVX600A, a model for autonomous application that was released early in April.

HX-CVX603A offers full support for reliable and consistent satellite signal tracking, including GPS, GLONASS, Galileo, BeiDou, IRNSS, SBAS, as well as L-Band correction service. It adopts Harxon’s patented phase balanced four point feeding technology and multipath suppression structure with excellent suppression effect, ensuring 2mm positioning accuracy within a high vibration environment.

It is also trustworthy, with its outstanding zenith gain curve. The maximum gain of L1 band reaches 4.5dB, the gain of most frequency bands in the bandwidth is larger than 3dB, the maximum gain of L2 band reaches 4dB, all of these parameters ensure reliable and consistent signal tracking. It has ideal low elevation tracking performance with most of the frequency band larger than -4dB, making it a great choice for applications that subject to high vibration, harsh environments and blockages.

The housing of the antenna uses PC+PBT material which has good flexibility and acid-base corrosion resistance. The enclosure design is specifically developed with IP67 standard for tough environments. The M18 screw enables easy installation for outdoor operations.


The introduction of Harxon’s new mini choke ring antenna HX-CGX611A, adds another competitive model to Harxon’s choke ring antenna series. In comparison with the earlier HX-CGX601A, the HX-CGX611A is smaller in dimension, without compromising performance. The HX-CGX601A is a 3D choke ring antenna with market-proven positioning accuracy, reliability and anti-multipath rejection performance.

The miniature choke ring antenna HX-CGX611A is smaller than the HX-CGX601 by 50% both in diameter and height, measuring just 185mm in diameter, 148mm high and weighing 2KG, yet it maintains the great performance as it’s predecessor.

The HX-CGX611A high performance base station antenna covers full frequency satellite signal tracking. The maximum gain in L1, L2 reaches 6.5dB, ensuring superior signal sensitivity. The adopted Harxon patented multi-point feeding technology of this antenna ensures greater phase center stability for sub-millimeter positioning accuracy, making it the best choice for base station, bridge, high building deformation and geological monitoring.

The HX-CGX611A achieves a greater gain and axis ratio of low elevation angle, with more than -4dB of low elevation gain and the axis ratio of 20 degree elevation less than 2dB, which ensures reliable signal tracking under blockages and in harsh environments.

The LNA of the HX-CGX611A displays extraordinary out-of-band rejection performance and restrains unwanted electromagnetic interference from complex conditions such as power grids, communication base stations, or radio modems.

HX-CGX611A is IP67 compliant to withstand dust and water ingress. The MTBF is over 30,000 hours, enabling endurance outdoor operations in tough environments, extreme temperatures, and amidst humid, salty and foggy conditions.
