    Helical Antenna

    full-band helical antenna specification
    创始人2025-01-11

    TDXL-GGBR8I05 is an active helical antenna that supports all-band satellite signal reception. The antenna adopts multi-arm structure to achieve dual-frequency reception, supporting the dual-frequency satellite navigation signals reception from BDS, GPS, GLONASS, and Galileo systems, as well as Satellite-Based Augmentation System (SBAS) L-Band. 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、The antenna shell is not easy to deform, features high intensity, waterproof and resistance in extreme temperature fluctuation. It provides protection for the antenna's long-term outdoor operation.
