Helix Antenna
LH-105AR-D / LH-105AR-DC / LH-105A2-B
LH-105AR-DC and LH-105AR-D and LH-105A2-B is an active dual-frequency GNSS antenna for L1 and L5 bands of GPS/QZSS, GLONASS, GALILEO, BEIDOU and IRNSS. The antenna is light and low power consumption that is ideal for applications requiring RTK level positioning accuracy, such as self-driving vehicle, drone display, aerial photography, high precision mapping, remote sensing, traffic control and public security.
