Some typing errors like in Figures 23 and 24 must be corrected from "n = 1" to "n = 4" according to the kind suggestion of our colleagues. Wave impedance does not deal with antenna performance, but instead with wave propagation. However, the calculations have been performed by means of software WIPL-D according to Figure 1 and for several antenna heights. These results are presented in Tables 1 and 2 along the x- and y-axes in numerical form. In this article, the theoretical transmitting top-loaded monopole antenna gain GT (dBi) corresponds to its directivity DT (dBi) according to Table 3 because it was calculated over perfect ground (no losses); in this case, at the frequency of f = 200 kHz. Traditionally, any analyzed transmitting monopole— its radiated waves reflected by perfect ground—are taken into account as produced by the antenna image underground. The image effect is increasing the antenna gain, effective antenna length, and antenna factor. Its transmitting equivalent area AeT can be calculated by the antenna numerical gain gT through the isotropic source effective area. Equations for these calculations are shown.

作者对“关于‘短中频天线性能’的评论”[致编辑的信]

根据我们同事的善意建议，必须将某些输入错误（例如图 23 和 24）从“n = 1”更正为“n = 4”。波阻抗与天线性能无关，而是与波传播有关。然而，计算是通过软件 WIPL-D 根据图 1 和几个天线高度进行的。这些结果以数字形式沿 x 轴和 y 轴列在表 1 和表 2 中。在本文中，理论发射顶部加载单极天线增益 GT (dBi) 对应于表 3 中的方向性 DT (dBi)，因为它是在完美地面上计算的（无损耗）；在这种情况下，频率为 f = 200 kHz。传统上，任何被分析的发射单极子——它的辐射波被完美的地面反射——都被考虑为地下天线图像产生的。镜像效应会增加天线增益、有效天线长度和天线系数。其发射等效面积AeT可由天线数值增益gT通过各向同性源有效面积计算得出。显示了这些计算的方程式。
