Checking the Digital-Signal Strength
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.
