Abstract
This work describes a campaign of measures of the characteristics of the propagation channel for Digital TV, recently carried on the metropolitan region of Sao Paulo. The measurements had been aimed to determine the propagation loss, the reception threshold and signal delay profiles in different situations of reception in urban environments. This paper presents preliminary results including the analysis of the propagation loss with in the distance in blockage and visibility conditions. Examples of measured delay profiles in conditions with and without line of sight are also presented.
