Welcome to the forum, cpd:

The set up actually works really well, with one exception. FOX (6.1) is laggy and displays green pixelation/jitters.
I notice that the signal from Fox is coming in from a little different angle than the other signals. There could be a tree or some other object in its signal path.

HTPC set up
What tuner are you using?

How well does the Leaf work with the TV tuner vs the HTPC tuner?

Does the TV tuner or the HTPC tuner have readouts of signal strength or more important signal quality to help you position the antenna?

I agree with ADTech, you must put the antenna where the best signal exists.

I suspect multipath reflections and tuner overload. WTMJ has a Noise Margin of 75.1 dB.

You could test the overload theory by inserting an attenuator in the coax line.

You can add a length of coax using an F-81 adapter to try different antenna locations.

Can someone recommend a different antenna that would work for all stations?
There are other indoor antennas that might work better because they have reflectors that make them more directional to reduce the pickup of reflections, but you might not like how they look. The Antennas Direct C2V would be one.

I don't like computers, and have yet to find one that I would call user friendly. I only tolerate them for what they can do for me. I never have understood why anyone would want to watch TV on a computer instead of a TV.

I see a lot of trees in your area. See attachment 1.

scroll down to Trees and UHF

I also see that you have some strong local FM signals that might interfere with TV reception. See attachment 2. You should insert an FM filter in the coax line.
