I have been playing around with the placement of my antenna and have noticed for my PBS station the stream is shuttering, pixelated and sound issues when I watch it on my Apple TV. Reading around it sounds like signal quality is more important than strength, but when I use an app like Signal GH I see Quality around 80% and Strength around 65%.
My other channels seem to be fine and don’t see these issues. What things can I look at to see why this one station is having issues?
