The Bottom Line: This antenna appears to be similar to your everyday average digital/HDTV antenna. It doesn't come with any special features that make it stand out but as always, Channel Master produces high quality antennas. If you are looking for an antenna for everyday use where signals are a little to weak for crisp pick up then this one would work out quite nicely.
