    Helical Antenna

    TDXL-900M multi-satellite multi-frequency helical antenna
    创始人2025-01-11

    TDXL-900M is a full-band active helical antenna designed with multi-arm helical technology, supporting the reception of satellite navigation signals from BDS, GPS, GLONASS and dual-band in GALILEO system, as well as Satellite-Based Augmentation System (SBAS) L-Band. It could meet the current requirements for multi-system compatibility and high-precision measurement, making it widely applicable 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.
