1. Using multi-arm helical technique, the antenna enables the right circular polarization and phase center performance, as well as minimizes the impact of measuring error;

2. The antenna unit offers high gain and minimal gain roll-off, providing excellent reception of low elevation satellite signals and ensuring normal reception in severely obscured locations.

3.It is equipped with a dustproof, waterproof, and shock-resistant outer casing, providing protection for long-term outdoor operation.
