Unlike analog channels, which can vary in reception quality from “snowy” to clear, digital (HDTV) channels have either perfect 
reception quality or you will not receive them at all. So, unlike analog channels, you cannot fine tune a digital channel.
You can, however, adjust your antenna to improve the reception of available digital channels.
