The frequency correlation characteristics of shadowing over television bands in a suburban area are evaluated. Some papers report that shadowing losses are high frequency correlated. However, although the frequency correlations can be modelled as a function of the frequency differences are expected, conventional works only present correlation analyses between two or three channels. The correlations have shown an exponential decrease in proportion to the frequency differences based on several massive datasets measured over the television bands. In addition, the empirical model for the characteristics of the frequency correlations is discussed. An empirical model that consists of two exponential decay models is proposed, and show the R ‐squared value for the experimental value is ∼1.
