GNSS Accessories - AX3705 640x340px.png
The AX3705 is a helix antenna that supports four satellite constellations and dual frequencies, which is designed for UAV systems and mobile devices. It can be used in aerial photography, telemetry technology, disaster monitoring, traffic patrol, security monitoring, etc.
This helix antenna has exceptional pattern control, polarization purity, and high efficiency in a very compact form factor. The antenna has a high gain and a wide beam width to ensure that satellite signals can be received at low elevation angles.
