This research study compares simulations obtained using deterministic, statistical, and semi-deterministic propagation models to measurements obtained of digital terrestrial television signal coverage for urban and rural environments in Colombia. A propagation model is selected that is most similar to the conditions found in the Colombian rural territory. This is to be used in the planning of digital terrestrial television networks in the UHF band having an error coefficient that can be compensated by applying correction factors. Simulation analyses show that the propagation model that is best suited to the real television broadcasting scenario for Colombia corresponds to a combination of the ITU-R 525 deterministic models for clear line-of-sight environments. For obstructed line-of-sight environments, it is concluded that the Deygout 94 propagation model offers the best results.
