Description

Product Technical Features

The antenna utilizes multi-arm helical technology to ensure right-hand circular polarization and phase center performance, minimizing the impact of measurement errors.

The antenna unit utilizes air dielectric, offering high gain and minimal gain roll-off.

This ensures excellent reception of satellite signals at low elevation angles, ensuring reliable reception even in heavily obscured environments.

The triple-proof housing provides long-term field protection.
