The multi-arm spiral technology is used to the right-hand circular polarization and phase center performance, and reduce the impact of measurement errors. The antenna unit uses air medium, which has the characteristics of high gain and small gain roll-off. It has a good reception effect on low-elevation satellite signals, ensuring that satellites can still be received normally in some places with severe obstruction. The triple-proof cover provides protection for the antenna to work in for a long time.
