    B1L1 antenna specification
    创始人2025-01-15

    TDXL-CZ2001 is a B1I, B1C and L1 dual-frequency navigation antenna designed with a lightweight and compact appearance, making it suitable for the fields with strict requirement on product weight like aerial vehicles and aviation. It features high gain and excellent low elevation gain, ensuring the antenna can reliably capture satellite signals even during high-speed movement.

    1、High low noise amplifier gain, compatible with longer cables.

    2、High passive gain, compact size and lightweight.

    3、The structure can be flexibly customized according to customer’s requirements to achieve conformal design with the end product.
