对线性宽边超增益阵列进行了数值计算。以总长度为四分之一波长的阵列为例，表明随着所需的定向增益的增加，需要巨大的电流来仅产生较小的辐射场。对于产生 8.5 功率增益的 9 元件阵列，必须将电流调整至正确值，精度优于 1011 分之一。效率低于 10-14%。
Numerical calculations have been made for linear broadside super-gain arrays. Using arrays having an over-all length of a quarter wavelength as an example, it is shown that as the required directive gain is increased, tremendous currents are required to produce only a small radiated field. For a 9-element array which produces a power gain of 8.5, the currents must be adjusted to their correct value to an accuracy of better than 1 part in 1011. The efficiency is less than 10-14 per cent.
