Another reason thatcan cause echoes is the reflection of the signal on large objects such as buildings ormountains. PRE-ECHOES are signals received before the main signal arrives.With the ECHOES function is possible to know the distance from where we are tothe transmitter or the object that has caused the echo. Thus, the installer can minimisethe effects of echoes on the facility. Knowing echoes, the installer is able to repositionthe antenna and therefore, reduce the effect of echoes received.This feature is only available for DVB-T/H y DVB-T2 signals. Therefore, youshould configure the TV EXPLORER HD in order to receive this type of signals.
