Popis:	This paper deals with the quality parameters of a television terrestrial signal received in the service area of a single-frequency DVB-T2 network, operating in the SISO mode (Single Input Single Output). The aim of the study is a practical assessment of selective fading frequency effect of the total signal and inter-symbol distortion of the signal at the input of the DVB-T2 receiver on the received signal quality. To achieve this goal, measurements of the qualitative indicators of the received signal were made in laboratory conditions. To receive television signals in the SFN DVB-T2 SISO cluster, it is preferable a directional antenna oriented to the incoming wave with the highest field strength. In this case, the interference waves effect of other cluster transmitters will be minimized. DVB-T2 noise-tolerance coding algorithms reliably compensate for the deterioration in the quality parameters of the received signal.
