High gain GNSS RTK Helix Antenna for UAV

GNSS helix antenna is designed for high precision positioning and offers superior satellite signal tracking, including GPS, GLONASS, GALILEO and Beidou. It has the characteristics of small size and light weight. It is widely used in navigation scheduling, tracking monitoring, measurement and control And other fields. Based on the four-arm helical antenna's low requirements for antenna attitude, it is especially suitable for many applications such as drone, such as aerial photography, traffic monitoring, remote telemetry, etc., and can also be applied to various handheld terminals, high-precision positioning modules, etc
