本指南提供了一套程序，可用于处理电源线AM广播信号的再辐射。它也可以应用于其他大型金属结构。 虽然本指南中列出的程序可能适用于其他中频（MF）源（如导航信标）的再辐射问题，但它们不适用于更高频率源（如电视广播信号）的再辐射问题。本指南不适用于再辐射结构对AM广播电台有害影响的法律证据。 在一些司法管辖区，政府监管或许可机构已规定了确定中波天线系统辐射方向图的具体程序。 其中一些程序也包含在国际条约和协议中，因此对签署管辖区的许可证持有人具有约束力。当获得中波天线系统运营许可的一方或多方与提议建造潜在再辐射结构的各方达成协议时，负责的政府机构或当局的程序应优先于本指南中概述的方法。

This guide provides a set of procedures that can be used to cope with reradiation of AM broadcast signals from power lines. It can also be applied to other large metallic structures. While the procedures listed in this guide may be applicable to reradiation problems from other medium frequency (MF) sources, such as navigation beacons, they are not intended to be applied to reradiation problems from higher frequency sources, such as television broadcast signals. This guide is not designed to be applied as legal evidence of harmful effects of a reradiating structure upon an AM broadcasting station. In some jurisdictions, the government regulatory or licensing authority has defined specific procedures for the determination of radiation patterns of medium wave antenna systems. Some of these procedures are also contained in international treaties and agreements, and as such are binding on the licensees of the signatory jurisdictions. When there is agreement between the party or parties who are licensed to operate the medium wave antenna system(s) in question and the parties proposing construction of potential reradiating structures, the procedures of the responsible government agency or authority shall have precedence over the method outlined in this guide.
