Present Knowledge of Propagation in the VHF and UHF TV Bands

Since the Ad Hoc report and the Commission's Sixth Report and Order establishing the present TV allocations, the Commission and others have been collecting measurement data on the propagation of signal at TV frequencies. In many cases data is now available where the earlier studies required extrapolation. It is the purpose of this report to review recent measurements and their analysis as they may affect the service and interference of TV broadcast stations. Reference will be made to areas where additional data and studies are desirable.
