AT400 GNSS Antenna for RTK

    1. Application

    AT400 is a professional antenna specifically designed for high-precision RTK/PPP applications such as surveying and mapping, precision agriculture, robotics, and machine control. It features a stable and reliable carrier phase center, a 150mm ground plane, and can stably receive almost all GNSS frequencies(L1/L2/L5/L6)) and signals.

    It supports L1/L2/L5/L6 bands [new updated].
