On the Use of Field Intensity Measurements for the Determination of Broadcast Station Coverage

This paper discusses the importance of adopting uniform standards designed to express the coverage obtained by broadcast transmitters in terms of the field intensities produced, and discusses the methods used by the authors. Illustrations are given of the methods used to determine coverage, to predict the effect of changes where transmission constants are known, and to determine interference conditions on the basis of given receiving set characteristics. The importance in the field of radio regulation of the establishment of certain fundamental principles defining the area throughout which a broadcast station is entitled to protection against interference from other stations and the conditions under which a listener is entitled to interference free reception is particularly stressed.
