2021/03/10 The mini choke ring antenna (right) with a traditionally sized antenna. Harxon, manufacturer of high-precision antennas in China, has released a new patented mini choke ring antenna, the HX-CSX610A. Weighing less than 2 kg, the tiny antenna could be considered the next generation of reference antenna trends, Harxon said. Harxon’s patent for the HX-CSX610A design includes its compact body, which offers flexible transportation and installation. Applications for the antenna include CORS stations, geodetic surveying and mapping, and other monitoring. The HX-CSX610A is armed with excellent phase center symmetry and multipath suppression across all GNSS constellations, Harxon said, including GPS L1/L2/L5, GLONASS L1/L2, BDS B1/B2/B3, Galileo E1/E2/E5ab/E6 and L band. For tracking performance, it can reach -0.5 dB at 20 degrees elevation. An anti-jamming improvement over previous antenna is a method of combining the choke-ring structure with spatial filtering multipath signal suppression. Hardware configurations meet IEC and GB standards. The antenna is water- and dust-proof.
