Technical features
1. Using multi-arm spiral technology to ensure right-hand circular polarization and phase center performance and reduce the impact of measurement error;
2. The antenna unit adopts air medium, which has the advantages of high gain and small gain roll-off, and has good effect on low-angle satellite signal reception, ensuring that the star can still be collected normally in some cases where the shielding is severe;
3. Three protective covers provide protection for the antenna in the field for a long time.
