    TDXL-HA400 BDS SINGLE-FREQUENCY HELICAL ANTENNA
    创始人2025-01-09

    TDXL-HA400 is a BDS single-frequency active helical antenna, featuring multi-arm helical technical design, supporting the reception of B1I, B1C, B1A bands satellite navigation signals from BD3 system. It could meet the current requirements for high-precision measurement and is widely applied in portable equipment, UAVs, navigation timing 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.
