Harxon HX-CSX231A Embedded GNSS Antenna


Embedded Full Frequency GNSS Antenna for Lawn Mowers



The HX-CSX231A embedded full-frequency GNSS antenna from Harxon is a high gain, small size and compact active GNSS antenna that provides reliable and consistent positioning services for high dynamic applications such as small robots and autonomous vehicles. This affordable antenna features small size, light weight and stable performance.

The HX-CSX231A is designed with plane antenna element with electromagnetic band gap structure and adopts low-loss microwave materials, which makes the antenna smaller in size, lighter in weight and improved in performance.

The HX-CSX231A offers full support for superior satellite signals tracking. It offers a very stable phase center variation with advanced multipoint feeding technology, ensures excellent positioning accuracy.

This antenna exhibits superior 4.5dBi high gain performance with ultralow signal loss. It also delivers wide beam width that covers wide frequencies with high marginal gain, perfect option in complex environments.

The advanced LNA of HX-CSX231A excels in improved signal filtering, out-of-band rejection, restrained unwanted electromagnetic interferences and strong multi-path reduction capacity.
