    创始人2025-01-13

    TDXL-KGR0401 is a BDS 4B3 anti-jamming array antenna, featuring compact overall size, high unit gain and good consistency among anti-jamming units. It offers wide beam pattern, excellent high and low elevation performance, as well as strong capabilities against single and multiple jamming. Made from special materials, the antenna is equipped with a low-profile design, allowing for better integration with customer’s terminal products. It also exhibits excellent resistance to extreme temperature fluctuation and corrosion, making it widely applicable in shipborne, ship-mounted, vehicle-mounted and other fields.

    1、The antenna’s anti-jamming units are symmetrically designed, ensuring consistent gain for each unit;

    2、It features a high degree of isolation between unit ports;

    3、It offers excellent circular polarization ratio and gain bandwidth;

    4、It can be flexibly customized in terms of operating frequency, size, and structure according to customer’s requirements.
