Freeview is a good and cheap option in areas where the analogue signal does not offer a decent picture. Sometimes experience and top quality products used in the installation are not enough. There are factors beyond our control such as the distance from the transmitter, overhead power lines or tall buildings which may cause interference and/or prevent the reception of the signal. In these cases a top of the range digital TV aerial can help obtain the signal necessary for the digital channels and a Freeview box will do the rest, delivering a perfect picture where analogue systems fail.
