    创始人2025-01-14

    TDXL-230MH BDS spiral antenna adopts eight-arm coupling and four-point feed technical, supporting the reception of B1I, B1C, L1, G1 and B3I satellite navigation signals. 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、Using multi-arm multi-feed zero phase center technique, the antenna enables the RHCP and phase center stability.

    2、Sophisticated low noise, high gain amplification and excellent out-of-band rejection.

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

    4、The antenna shell features waterproof and resistance in extreme temperature fluctuation, providing protection for the antenna's long-term outdoor operation.
