    Helical Antenna

    BDS helical antenna specification
    创始人2025-01-11

    TDXL-GGBR6I05 BDS helical antenna (high power resistance electric fields) adopts eight-arm coupling and four-point feed technical, supporting BD2 B1I, B1C and B3I satellite signals reception. Built-in low-noise amplifier with a two-stage filter offering excellent out-of-band rejection and strong anti-interference 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-power limiter in front, preventing the BDS antenna from being destroyed in strong electric field.

    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.
