Model: AN502
TOPGNSS AN502 The antenna has a built-in GNSS L1+L2 helical antenna design, which has the characteristics of small size, high positioning accuracy, and light weight, which can meet the high-precision rtk positioning requirements.
Feature 1: Lightweight. The total weight of the antenna is less than 50g, which is suitable for high-precision navigation equipment for unmanned aerial vehicles, small unmanned vehicles, and unmanned ships. Can greatly reduce the load burden.
Feature 2: Easy to install, the antenna adopts standard SMA connector for feeding and transmission.
Feature 3: The antenna has a four-arm spiral structure, excellent omnidirectional radiation characteristics, better low-elevation gain and wide-angle circular polarization characteristics, and can receive more low-elevation satellite signals.
