Harxon HX-CHX602A GNSS Helix Antenna


GPS L1/L2/L5 + BeiDou B1/B2/B3 + GLONASS G1/G2/G3 + Galileo E1/E5a/E5b/E6 + L-Band



The HX-CHX602A GNSS helix antenna from Harxon is a multi-constellation full frequency high gain geodetic surveying antenna. This small form factor antenna employs a foldable design that allows a maximum of 90 degree bending angle for superior GNSS signal availability while integrated with surveying terminals as pad and consoles in the field. Its high sensitivity, low power consumption, small dimensions, flexible angle of signal reception make it a great match for geodetic surveying applications.

The Harxon HX-CHX602A offers full support for reliable and consistent satellite signals tracking, including GPS, GLONASS, Galileo and BeiDou, as well as L-Band. It also exhibits a very stable phase center by adopting multipoint feeding technology, exceptional low elevation satellite tracking with symmetric radiation patterns, high gain with ultralow signal loss, as well as outstanding wide-angle circular polarization (WACP) ensures remarkable positioning

The HX-CHX602A is able to track any visible satellites under challenging conditions, providing the positioning solutions with higher precision and reliable data. The ability to track low elevation satellites while maintaining high gain makes this antenna an excellent choice for any applications where the sky is partially visible, such as plant protection, tree canopy, or for UAV power patrol, GIS surveying where high precision is needed.

The advanced LNA (Low Noise Amplifier) excels in improved signal filtering and out-of-band rejection and restraints unwanted electromagnetic interferences, plus strong multi-path reduction capacity over all GNSS frequency bands, providing strong anti-interference performance for consistent and reliable GNSS signals, even under complicated environments such as power grids, communication base stations or radio.

The HX-CHX602A adopts a rugged small form factor foldable design that allows a maximum of 90 degree bending angle, providing the most flexible GNSS signal reception angle for robust signal availability of the surveying control terminals. This foldable design ensures reliable performance even after long-term repeated bending operations. The Harxon patented IP65 waterproof enclosure ensures the antenna long term reliable performance even under harsh
environments as rain, dust, splash or sunlight.
