Revision Standard – Active. A set of procedures to be followed to cope with reradiation of AM broadcast signals from power lines and otherre large metallic structures is provided. Reradiation may be described as electromagnetic waves radiated from a structure that has parasitically picked up a signal from the environment. A simplified prediction technique called a survey is described to determine which structures could possibly cause a problem. Guidelines for measurements and data analysis are included.
