This multi-arm spiral antenna is designed using advanced technology to ensure right-hand circular polarization and phase center performance, minimizing measurement errors. It also utilizes an air medium, which provides high gain and minimal gain roll-off.

The antenna unit has excellent reception for low-elevation satellite signals, allowing for normal reception even in areas with tight obscuration. Additionally, the three-proof outer cover ensures the antenna can work reliably in the field for extended periods of time.

Suitable for applications that require small size and weight, such as drones, small RTKs, and sub-meter flat-panel hand-held devices.

It supports L1 and L2 dual-band satellite navigation signal reception for Beidou II/GPS/GLONASS/GALILEO systems, ensuring compatibility with multiple systems and meeting the demand for high-accuracy measurement. It can be widely used in high-accuracy navigation and positioning applications, including portable equipment and drones.
