If you're only interested in the local signals, that's fine. I brought it up because many folks are trying to get every possible signal.
If we concentrate on the stronger signals to the NE, the next step would be to test reception with your existing antenna outside, with a view to the NE. You would need an RG-6 cable and an F-81 barrel connector...

At the same time, you can explore reception conditions at windows with a NE view as well as conditions in the attic.
