Description

Product Technical Features

The multi-arm spiral technique is adopted to ensure the right-handed circular polarization and phase center performance, and reduce the influence of measurement errors.
The antenna unit has the characteristics of high gain and small gain roll down, which is good for receiving signals from low elevation satellites.
Exquisite low noise, high gain amplification and excellent out-of-band suppression;
Small size, light weight, easy to carry and install.

Product Application
It is suitable for the occasions where the volume and weight are required, such as drones, micro RTK, sub-meter handheld phones/tablets and other portable devices.
