The launch of the digital terrestrial broadcasting in Japan is scheduled in 2003. To determine the suitable link budget for fixed reception, fluctuations of the field strength of digital and analog television were measured in the area of Tokyo-Tower station eleven months. The field strength value for 99% of the time of the digital television was -1.8dB to the center value. On the other hand, the corresponding value of the analog television was -11.7dB. This difference between the two values suggests that the margin for 99% of the time in the digital television broadcasting is expected smaller than that of the conventional analog television broadcasting.
