Abstract :
The paper analyses the effect of a high viaduct and a train on TV signals from two side: shelter effect and reflection effect, based on the theory of electric wave propagation and gives the measured data as confirmation. By comparison and analysis, we can know how and to what extent the TV signal will be affected by all kinds of parameters.
