The prediction of field strength in the frequency range 30 - 1000 MHz
Abstract
The background of the BBC's involvement in propagation measurement at VHF and UHF is outlined. Weaknesses in the original data are discussed. The accuracy of prediction is related to the accuracy of measurement as illustrated by an experiment dating to the development period of an interim BBC prediction method for UHF, and the accuracy of the current path loss prediction method is discussed. Possible directions of future development in prediction methods are indicated and the objectives of the BBC's research in this area are outlined.
