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

    TDXL-HA400 is a multi-satellite, single-frequency active spiral antenna designed with multi-arm spiral technology, supporting the reception of satellite navigation signals from BDS, GPS, GLONASS and L1-band in GALILEO system. It could meet the current requirements for multi-system compatibility and high-precision measurement, making it widely applicable in portable equipment, UAVs, navigation timing and other high-precision navigation and positioning locations. It can be customized according to customer’s requirements.

    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.
