OEM GNSS Antenna HX-CSX383A KEY FEATURES • Supports GPS, GLONASS, Galileo, BeiDou, QZSS, IRNSS and L-band correction service • Supports WiFi,4G • Strong anti-Interference performance • Powerful system compatibility, easy for machine integration HX-CSX383A is an embedded multi-constellation multi-frequency GNSS antenna that covers GPS, GLONASS, BDS, and GALILEO and is also compatible with WiFi and 4G. It can be widely used in geodetic surveying, marine surveying, channel surveying, dredging surveying, seismic monitoring, bridge deformation monitoring, landslide monitoring, port container operations, and other occasions. GREAT COMPATIBILITY FOR SOLID RELIABILITY This versatile antenna adopts a compact design that combines GNSS antenna, WiFi antennas and 4G antenna, delivering great compatibility to be integrated into RTK applications. The layout of this multifunction antenna is specifically designed for realizing a perfect isolation effect among the different antennas embedded and ensuring outstanding reduction of interrelated influence. RELIABLE AND ROBUST STRUCTURE Utilizing self-developed air-spaced technology and low consumption microwave materials, GNSS antenna substrate is molded integrally through a mold, resulting in lower loss, lighter weight, smaller antenna dimensions, higher precision, good consistency, and more stable and reliable electrical performance. STRONG ANTI-INTERFERENCE PERFORMANCE 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, and broadcast stations. STABLE PHASE CENTER FOR REMARKABLE PERFORMANCE It features multi-point feeding capability, guaranteeing a reliable phase center for millimeter positioning accuracy. The BT and 4G antenna is placed around the GNSS, ensuring good structural symmetry, and ensuring the consistency of the positioning antenna's phase center. TRACKING IN COMPLEX ENVIRONMENTS This antenna exhibits superior high gain performance with ultralow signal loss, ensuring reliable satellite signal tracking. It also delivers wide beam width that covers wide frequencies with high marginal gain. These features in turn ensure the antenna a robust signal availability even in low elevation, making the antenna a perfect option in complex environments that have blockage, such as tree canopy and buildings.
