    Helical Antenna

    TDXL-803M dual-frequency BDS helical antenna
    创始人2025-01-09

    TDXL-803M is a BDS dual-frequency active helical antenna designed with multi-arm helical technology, supporting the reception of satellite navigation signals from BD3 system. It could meet the current requirements for multi-frequency points compatibility and high-precision measurement and it is widely applied in portable equipment, UAVs and other high-precision navigation and positioning locations.

    1、Using multi-arm helical technique, the antenna enables the right circular polarization and phase center performance, as well as minimizes the impact of measuring 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.
