Multi-frequency (L1, L2, L5) helix antenna H20 is a high performance GNSS antenna designed for high-precision positioning services, with a stable phase center that maintains high gain at lower elevation positions, providing excellent satellite signal tracking. The antenna has a compact size, lightweight, and low power consumption, which can effectively reduce the load on the drone (UAV) and extend the battery life of the device.

The multi-frequency helical antenna H20 is widely used in unmanned aerial vehicles, portable navigation devices, and compact RTK equipment.
