Preparing the conversion to the digital broadcasting system, we are deciding broadcasting network plan and interference protection area, using the measured receiving electric field level from the digital broadcasting station. However, the essential researches are needed about a receiving electric field level, because a digital TV (DTV) broadcasting receiver has been improved and an actual receiving environment should be considered. In this paper, the measured data were classified with domestic terrain of line of sight (LOS) and those of non-LOS, and effective receiving electric field level was proposed based on the LOS data. It is known that receiving electric field-level of 48 ㏈uV/m or more should be required for receiving rate of 90% and 50 ㏈uV/m for that of 95%, on the basis of the information of domestic terrain LOS.
