The Long Period Characteristics of Long Distance Propagation on VHF Television Broadcasting Waves

Abstract

The analysis of the propagation characteristics presented in the report was all measured automatically, and data obtained was processed by computer. The VHF TV broadcasting signals from the Tokyo Tower were received at long-distance propagation path of 118km and then field strength was analyzed. With respect to the seasonal variation in fading, the level variation increases in summer season and decreares in winter season.
