This signal report from rabbitears.info shows the channels you want:

It does look like you will need two antennas to get everything you want. The attic antenna is for UHF and VHF, but since it seems to be doing well for WCCU Fox, I would use it just for Fox.

Should it go in the attic also?
Your second antenna, for the signals from the west, can be inside or outside; you will need to do some more experiments.

I could use the Winegard that's out in my yard, or there's a open box deal on a C2V at Best Buy for $35.
Neither one of those antennas is suitable for the signals from the west, because they don't have enough gain for WILL PBS on VHF-High channel 9. You need a UHF/VHF combo antenna like the Winegard HD7694P for the channels from the west.

Can I use a splitter in reverse to combine them?
A splitter in reverse CAN be used to combine two antennas aimed in different directions, but it doesn't always work; you just have to try it. You would be combining UHF signals from two antennas that would interfere with each other if they don't arrive at the combining point in phase (arrive at the same instant).

If you don't get all the channels after combining that you had when the antennas were separate, then combining with a splitter in reverse doesn't work for your location.

Or does it need to be a "combiner"? The UVSJ has been mentioned, but when I google it I'm not finding one.
The UVSJ (UHF-VHF-Separator-Joiner) is a type of combiner; it combines a UHF antenna with a VHF antenna, but not two antennas that both receive UHF signals. In your case, for example, if you only wanted to receive just Fox 26 and PBS 9, you could use a UVSJ to combine a UHF and a VHF antenna that are aimed in different directions.

UVSJs (AKA UHF/VHF Diplexer) are getting hard to find. This is what they look like:

I'm concerned once I start adding TVs I'm going to have trouble, and the consensus seems to be NO AMP because of WICD being so close. This has been challenging but I'm making good progress. Thanks again for all your help!
Based on your signal report, the consensus is that a preamp should not be used because WICD is extremely strong. But, the actual WICD signal at your location might be a lot weaker because trees block TV signals (the report doesn't know about the trees), and since you are so close to the WICD tower, the strongest part of the signal beam might be well above your location. Also, since neither antenna will be aimed at WICD, that will make it weaker.

If you had a signal level meter, you could measure the strength of the signals, but you might have a TV with a relative signal strength indicator in the menu. With it, you could find out just how weak a signal can be and still be received.

With the proper antennas, aimed in the correct direction, WCCU and the signals from the west should be strong enough. Once you have each antenna able to pick up the channels you want, then we can talk about the combining options. If the signals are still too weak after splitting, then a distribution amp can be added before the splitter.
