Dual-frequency (L1, L2) helical antenna H1 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 is small in size, light in weight and low in power consumption, which can effectively reduce the load of the device and improve the battery life of the device.

The H1 dual-frequency helical antenna is widely used in unmanned driving, portable navigation devices and compact RTK equipment.
