If you mean lower quality as weaker signal, perhaps the broadcaster has
reduced power on the analog signal. Doesn't seem to make sense as analog
and digital are separate frequencies. But analog 18 out of Eau Claire
and analog 19 out of La Crosse are extremely weak to nothing for me
during the day. But late at night it seems the digital signals are
turned off and the analog signals start coming in again.
I can't confirm as I don't have a digital TV, plus the digital power is
so low (21 kW for 18.1, 174 kW for 19.1 according to tvfool.com) I
probably couldn't get them anyway where I am, even with a 70 foot tower.
