Here’s my TVFool http://www.tvfool.com/?option=com_wrapper&Itemid=29&q=id%3dec2f385689757 b

With Dayton and Cincy at about 200° apart I had 2 antenna A/B to try to get everything. I started with just a 71” from Radio Shack that did one or the other pretty well, but not both. It would pick up Cincy off of the back, but not well enough. I added an RCA ANT751R for Cincy, but still had dropouts and weak signals. After searching for a bi-directional antenna, I ended up making the Stealth Hawk. It was an easy build and pretty much free (already had everything I needed) and does as well if not better than the 2 antenna combined. I get pretty much 80% or better on everything I had before. And now Iget channel 25.1 (broadcast on 47) at about 30%. WDYC (36) WKOI (39) & WCVN(24) are 0-10%. But, I don’t get WOTH (20), WBQC (25) or WRGT (30).

Looking at the TVFool it seems I should be getting these(and better reception on 47), but can’t seem to bring them in regardless of where I’m aiming. I never got any of them with the other antenna either (or even knew they existed) so maybe it’s something between me and the broadcasts that’s keeping them out, but I get 9 & 12 @ 100% and it seems at least 47, 25 & 36 are in the same place.

Any suggestions would be helpful.

Looks like you're close enough to the Cincy stations that they should be fairly easy to get. I'm guessing you're using the antenna indoors, not outdoors?
Dayton stations probably aren't going to be possible with any antenna used indoors. I've got an old style CM4228 and a 91XG antenna mounted on the roof. With either antenna pointed SW I get
Cincy channels fine and Dayton off the back side. I only have the #4228 hooked up now here in Clermont County. Long story short.....get the antenna outside if at all possible.

Antenna's outside. About 30' high.
I get all the Dayton fine (80%+). It's just those few Cincy channels that give me trouble. I might be Clear Channel (now in kenwood) has transmitters or something on the roof that's messing with my signal.
I was pretty amazed when I put the little antenna up and get better signal than my 71".

How else is the WEBN frog going to control the fireworks on Sunday? Seriously, I don't think that's the issue unless you have obstacles directly in your line-of-sight path like trees. You could also be dealing with multi-path, which is difficult to diagnose in the digital era. (In the analog era, you would see ghosting in the picture.) From your location, you should get everything from Cincinnati and perhaps only have issues with WKOI (RF 39, virtual 43) because it's off-axis.

Are you using an amplifier (installed at the TV) or pre-amplifier (installed at the antenna, but powered close to the TV)? That may cause overloading and wash out your weaker channels. Are you using new RG-59 cable from the antennas to your TV? If you're using old and weathered cable, it could be losing signal. Or there could be a short in it. There's also a chance that your homemade antenna has a problem, especially if you also have a homemade balun.

P.S. WBQC is RF 47, virtual 25, so you're already getting that weakly. WRGT from Dayton can be tough to get in our general area because their transmitting antenna doesn't radiate a lot of power south. (See this link from TV Fool.) Nobody can get WOTH (RF 20, physical 38) because it's not broadcasting at the moment. Although there was an article in the Enquirer hinting that the new transmitting antenna for RF 20 was installed a few weeks ago...
