Introduction：
419 NJ 是由德国 Shwarzbeck 设计用于ISO11452-9手持式发射机抗扰度测试的产品，由深圳EUTTEST代理销售，它自带终端电阻和散热器，可在20MHz- 220 MHz 的频率范围内近距离进行高效抗扰度测试，线性极化的 419NJ 一般用于汽车行业等电磁兼容测试。
安装在扁平元件 419NJ 后表面的内置终端电阻可在很宽的频率范围内提供非常平坦的阻抗匹配，几乎让辐射元件 419NJ 和 EUT表面之间的距离无关。连接巴伦 NMHC 4MM 可以实现 4:1 阻抗变换，增加了419NJ 的输入电压范围。
如果您需要测试其他频率范围，请选择以下同类天线产品：
