    Helical Antenna

    Built-in multi-satellite multi-frequency helical antenna specification
    创始人2025-01-11

    TDXL-GGBR7I04 is a built-in active helical antenna that supports multi-satellite, multi-frequency signals reception. The antenna adopts multi-arm structure to achieve dual-frequency reception, supporting dual-frequency satellite navigation signals reception from BD2, GPS, GLONASS, and Galileo systems. It could meet the requirements for multi-system compatibility and high-precision measurement at present, making it widely applicable in portable equipment, UAVs and other high-precision navigation and positioning locations.

    1、The antenna has a high passive gain and excellent low elevation reception performance, ensuring normal satellite reception even in obscured environments.

    2、Using multi-arm multi-feed zero phase center technique, the antenna enables the RHCP and phase center stability.

    3、High LNA gain, low noise figure.

    4、Strong capacity in filter out-of-band rejection and antenna anti-jamming.

    5、Compact size, lightweight, portable and easy to install.

    6、Using partitioning technique, the antenna enables the phase center stability in all directions.
