    TDXL-HA300 BD3 handheld antenna
    创始人2025-01-09

    TDXL-HA300 is a BD3 handheld terminal satellite positioning antenna designed with folding helical arm technology, supporting the reception of B1I and B1C dual-frequency satellite navigation signals from BD3 system. It could meet the requirements for high-precision measurement and is widely applied in portable equipment and other high-precision navigation and positioning locations.


    1、Folding helical arm technology is adopted to achieve miniaturization while ensuring right circular polarization and phase center performance to minimize the impact of measurement error;

    2、The antenna unit offers high gain and minimal gain roll-off, providing excellent reception of low elevation satellite signals and ensuring normal reception in severely obscured locations.

    ​3、It is equipped with a dustproof, waterproof, and shock-resistant outer casing, providing protection for long-term outdoor operation.
