The digital terrestrial television which uses the electromagnetic wave of UHF band was started in December, 2003 and it will be shifted completely by July, 2011. In this paper, the electric field strength level is measured in the reception condition that is different of the distance and height and in city. As a result of the measurement, the following have been understood.
1. The electric field strength level decreases as the distance parts but the influence that buildings and landform give it is larger.
2. The electric field strength level increases as the reception point rises and are almost constant.
3. The distance from buildings and the direction of the electromagnetic wave influence the electric field strength level because of the diffraction of it.
4. The amount of attenuation at the electric field strength level is large in the city because the building is large and it is overcrowded.
The study is critical data in link budget analysis of the electromagnetic wave of the digital terrestrial television.
