Before I put in a digital antenna I always wondered what the signal quality was going to be like on my TV. In the video below you can see that the quality is great. I took this video during that day so the screen is a bit washed out by sunlight. However this is a 50 inch plasma TV and the signal quality is true HD TV for most channels. The way it works with over the air signals is that it is 100% digital and so you either get the channel with full quality or you do not. It is not like the old days when you see a snowy or fuzzy display – it is either perfect or not on at all.
