D-Helix® Antenna
Place of Origin： China
D-Helix® antenna covers the four major satellite navigation systems of GPS, GLONASS, BDS, GALILEO full-band signals, and can support L-Band satellite-based enhanced signals. The high gain of the antenna unit, its excellent low elevation angle and anti-jamming performance, ensure the antenna's all-weather satellite tracking ability in various complex environments. It is suitable for high-precision operation scenes with severe occlusion and poor signal quality, such as drones, intelligent driving and other fields.
