    Short Message Antenna

    TDXL-BLS4002 BDS short message combined antenna
    创始人2025-01-08

    TDXL-BLS4002 is a built-in antenna designed for receiving BDS B3I, B1I, S-band satellite signals and transmitting BDS L-band 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. It is widely applied in ship-borne, vehicle-mounted, handset 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 unit features an offset feed design, offering high gain, a wide directional beam, and excellent low-elevation signal reception, ensuring normal reception in special occasions where the signal is severely obscured.

    3. Excellent circular polarization axial ratio and gain bandwidth.

    4. Compact size and easy to integrate.

    5. Can be flexible customized according to customer’s request.
