So far I had an antenna, the signal with 15dB amplified. This had zurfolge a blurred image and every time a car / bus to the apartment drove jerky image for a few seconds and was completely gone. So I looked around and came across by other reviews on this antenna. The picture was much better and the disturbances have become much less. Despite falls from time to time the image when a bus passes. Occasional disturbances there is also because the antenna may be naturally never perfectly aligned for each transmitter. Basically, I'm quite happy with it because it represents a significant improvement to the condition of it. As for the HD compatibility, I can only say that the image after all far to the rankommt a DVD.
