    Dual-satellite dual-frequency antenna
    创始人2025-01-15

    TDXL-DZ2002 is a dual-satellite dual-frequency antenna designed for receiving GPS L1, BDS B1I and B1C satellite signals. The antenna unit offers high gain, wide directional beam, and excellent high and low elevation performance. The antenna with special craft makes it possible to resist extreme temperature fluctuation and corrosion, which can do outdoor work for a long time. The antenna is widely applied in ship-borne, vehicle-mounted and other fields.

    1、The antenna part adopts symmetrical design to minimize the impact of the precision error and ensure the phase center stability.

    2、The antenna part adopts offset feed design, offering high gain, wide directional beam and good low elevation signal receiving effect, ensuring the normal reception in special occasions where severe obscured.

    3、The RF circuit is equipped with front filter, which enhances the whole ability to resist out-of-band interference.
