AT130 Helix Antenna
Other
Overview
The antenna's small size (Φ107×43mm) and IP67-level waterproof and dustproof certification make it rugged enough for outdoor use, including in harsh weather conditions. Delivers a high gain of 3.5dBi, ensuring superior tracking performance even at low elevation angles. The AT130 Helix Antenna ensures high stability and repeatability at the phase center, making it optimal for applications requiring precise GNSS positioning, such as UAV, GIS, RTK and related mobile devices.
