That's right. And you'll also need a pre-amp. A very high gain antenna can pull a negative NM signal up into positive territory, but not by much. You don't want to lose that signal to things like cable loss, splitters, and the Noise Figure of your receiver, so a pre-amp is the way to go. A pre-amp will let you preserve as much signal quality as possible (right after the antenna) by boosting the signal before all of those "downstream" losses.

They are pretty close for the most part. I would expect the 3020 to do just a tiny bit better on UHF channels and the HBU-55 to do a little better on the high-VHF channels. The 3020 also supports low-VHF channels, but you don't have any in your area to worry about.
