A low-cost antenna dedicated to wide range lightning magnetic field registration was presented. The bidirectional magnetic field sensor with preamplifier circuit was developed to operate at the local lightning detection station in Rzeszow, Poland. A calibration factor and effective area of the sensor were obtained from laboratory measurements. The calibration setup was made of a Helmholtz coil and arbitrary generator. The preamplifier was designed as a two stage circuit consisted of an integrator and amplifier. This construction linearized the sensor and fit it to the required antenna range. Measured frequency characteristics of the antenna showed a stable distribution of the calibration factor in the bandwidth corresponding to major components of cloud-to-ground lightning. Registrations from the station in Rzeszow were compared with corresponding data from the lightning location system and theoretical formulae for the lightning current estimation. Contrary to the most of commercially used lightning magnetic field antennae, this antenna was specifically designed for registration in a close and the middle distance of several kilometers from the lightning channel. Registration in this range can be applied for identification of lightning features not yet reported by modern lightning location systems.

提出了一种专用于大范围雷电磁场记录的低成本天线。具有前置放大器电路的双向磁场传感器是为在波兰热舒夫的当地雷电检测站工作而开发的。传感器的校准系数和有效面积是从实验室测量中获得的。校准设置由亥姆霍兹线圈和任意发生器组成。前置放大器设计为由积分器和放大器组成的两级电路。这种结构使传感器线性化，并使其适合所需的天线范围。天线的测得频率特性显示出校准因子在带宽中的稳定分布，该带宽对应于云对地闪电的主要成分。将热舒夫车站的注册信息与雷电定位系统的相应数据以及雷电流估计的理论公式进行了比较。与大多数商用雷电磁场天线相反，该天线是专门为在距离雷电通道几公里的近距离和中间距离内对准而设计的。此范围内的注册可用于识别现代闪电定位系统尚未报告的闪电特征。
