I have a Toshiba TV with built-in tuner that's been giving me trouble below 50% on the onscreen reception meter. Muddled pixelation is the best way to describe the picture on the lower VHF channels. Yet I have a RCA DT800B on a small TV in my computer room that shows between 45-50% at times and the picture seems perfect. Go figure. I've studdied my own results on TVFool and ordered a DB4 antenna for the attic which I'll split between 3 TVs but I was just curious.
