As Ratman said, the right antenna will depend upon where the antenna is mounted and which channels you want. First off, the TVFool report has a few errors because they are using a defective database to generate reports:
WHIO CBS is missing from your TVFool report, but it shows on this rabbitears.info report based on my estimate of your location:
It is the real channel number (also called physical channel or RF channel) that determines what antenna is needed.
VHF-Low, real channels 2-6
VHF-High, real channels 7-13
UHF, real channels 14-51
The virtual channel number (like 5.1 or 5-1) is a holdover from the analog TV days to maintain the identity of the station, and is what the TV displays. By convention, the virtual channel number is given in the decimal form to keep it from being confused with the real channel number.
I don't see any important VHF-Low channels on your reports, so you don't need a huge antenna that covers real channels 2-6. WLWD will be moving to channel 5 after repack by the FCC, but you probably will not need Daystar:
There is a good selection of strong channels from Dayton that are all UHF at the present time. I would suggest just Dayton, but if you must have Dayton and Cincinnati, you will need an antenna with a wide beamwidth like the Antennas Direct C2VJ or its replacement the C2MAX with the accessory reflector. Both only have a dipole for VHF-High channels like the weaker WKRC CBS on real channel 12, but you already have WHIO for CBS.
If you put an antenna in your attic, the signals will not go through a metal roof. If the end of the attic faces west and the wall is vinyl or wood siding, the signals might get through without too much loss; brick will be a little more difficult. Maybe you can show us some photos of the exterior construction.
Trees can block TV signals, especially when they are wet. If you send me the coordinates of your proposed outdoor antenna location by PM to protect your privacy, I can look at the satellite view of the signal lines.
First get the signals you want on just one TV, splitting can come later. Try without a preamp first; your strongest signals might overload a preamp.
You must be prepared to do some experimentation to get what you want.
If the antenna is outside, the coax shield should be grounded with a grounding block that is connected to the house electrical system ground with 10 gauge copper wire for electrical safety and to reject interference. For further compliance with the electrical code (NEC), the mast should also be grounded in a similar manner to drain any buildup of static charge which will tend to discourage a strike, but the system will not survive a direct strike.

Most changes will be during Phase 6, 9/7 to 10/18 2019
