Signal Strength (Digital)
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 ne tune a digital channel. You can, however,
adjust your antenna to improve the reception of available digital channels.
If the signal strength meter indicates that the signal is weak, physically adjust your
antenna to increase the signal strength. Continue to adjust the antenna until you nd
the best position with the strongest signal.
