Harxon has released its next-generation triple-frequency Helix Antenna HX-CH7603A, which has excellent performance and high efficiency in a compact form factor, the company said. Harxon’s new-design helical antenna HX-CH7603A is capable of GPS L1/L2, GLONASS L1/L2 and BDS B1/B2/B3. Though compact, it provides high peak gain (more than 3.5 dBi) and wide beam width to ensure the signal receiving performance of satellite at low elevation angles. HX-CH7603A is equipped with an O-ring and gold-plated SMA (sub-miniature version A) connector that makes the antenna waterproof-grade, reaching IP67 once installed on a mating surface. The antenna is designed for applications requiring minimal integration effort or for retrofitting existing products. Features High gain (3.5dBi) with superior tracking performance Very low noise figure High stability and high repeatability at phase center Waterproof rubber ring Ultra light weight GIS and RTK applications Applications Military and security Aerial photographs Drone navigation High-precision navigation Mining equipment Autonomous Vehicle
