    Quadruple anti-jamming array antenna
    创始人2025-02-13

    TDXL-KGR4 810-OS is a full-band anti-jamming antenna, which effectively suppresses low elevation angle signals through the rational layout of four full-band spiral antenna elements, thereby achieving low elevation angle interference resistance. The antenna has excellent circular polarization characteristics and high consistency between elements. The array synthesis results in high top gain and a high roll-off factor, offering the antenna excellent low elevation angle interference resistance capabilities. The single antenna element with special craft makes it possible to resist extreme temperature fluctuation, corrosion, and UV rays. It can be widely applied in UAVs, carrier-borne, ship-mounted, vehicle-mounted and other various fields.

    1、The antenna's anti-jamming units are center-symmetrically designed, ensuring consistent gain for each antenna element;

    2、The appropriate spacing ensures a high degree of isolation between unit ports;

    3、Excellent top reception gain and roll-off characteristics, ensure that the antenna has excellent resistance to low elevation angle interference;

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

    5、Lightweight design, suitable for terminal devices with weight requirements.
