To get the most out of dtv gov maps, follow this precise workflow:
Producing reliable DTV GOV maps requires several kinds of data and modeling steps:
Terrain and land cover
Radio propagation models
Clutter and building loss models
Population and geography datasets
Measurement data
If the map shows "Poor" or "No Coverage" for the nearest major city, you may need a large, outdoor directional antenna mounted on a rotor, plus a pre-amplifier. The map helps you aim the antenna precisely at the transmitter coordinates provided in the station's data sheet.
