You are correct, thus if you want to get stations 120 miles away you have to
raise your antenna. Most likely, it would have to be above the treeline, but
we don't have mountains in Indiana either. Also it's wise to install an
amplifier as close to the antenna as possible for that long of a distance.
And I'd probably recommend a parabolic, I think those have the Highest gain
of any antenna type.
But I would suggest the antenna installers on TechAssist take the ball from
here.
