    Helical Antenna

    gps SINGLE-frequency HELICAL ANTENNA SPRCIFICATION
    创始人2025-01-11

    TDXL-GGBR5I05 is a GPS single-frequency helical antenna that adopts eight-arm coupling and four-point feed technical, supporting GPS L5 satellite signals reception. Built-in low-noise amplifier with a two-stage filter offering excellent out-of-band rejection and strong anti-jamming capability, ensuring normal operation in harsh electromagnetic environments. It meets high-precision measurement requirements and is suitable for applications with strict volume and weight constraints, such as handheld devices, tablets, UAVs, compact RTK and other portable equipment.

    1、The antenna has a high passive gain and excellent low elevation reception performance, ensuring normal satellite reception even in obscured environments.

    ​2、Using multi-arm multi-feed zero phase center technique, the antenna enables the RHCP and phase center stability.

    3、High LNA gain, low noise figure.

    4、Strong capacity in filter out-of-band rejection and antenna anti-jamming.

    5、Compact size, lightweight, portable and easy to install.

    6、The antenna shell is not easy to deform, features high intensity, waterproof and resistance in extreme temperature fluctuation. It provides protection for the antenna's long-term outdoor operation.
