What should be expected when we connect the new converter box. Should we expect new channels or is that just wishful thinking. Better reception should or would be expected and not considered unreasonable right?
If you get an analog station you should also get that stations digital channels. This is assuming that their digital channels are on the air. If you had a good analog signal with a good antenna you should have the same with digital.
With a poor analog signal you could maybe watch a snowy picture. With digital it either has sufficent signal for a picture and sound or you have nothing.
Over time as analog radio stations change over to digital if they have not already done so in your area. You should gradually have a better digital signal as the analog interence goes away.
