The good news is that the FL6550A does much better with UHF signals, real channels 14-51, than with VHF-High signals, 7-13.
The bad news is that the Flatwave has a built-in amplifier of unknown gain, that most likely will be overloaded by your very strong signals. Your strongest signal WTTE, has a Noise Margin of 71.5 dB.

The signal loss because of the attic location is difficult to predict, so I can't make any guarantees. Aluminum siding, stucco wire mesh, or aluminum foil heat barriers will block the signals. You need to make some tests with a temporary run of RG6 coax and try different locations in the attic with the antenna aimed at about 25 degrees magnetic.
If there are any trees or buildings in that direction, the signals will be blocked.
I suggest you try an Antennas Direct C2 or RCA ANT751 antenna without a preamp first to see how it does with the splitter. You could always add a distribution amp later, but I doubt that you will need it. Conversely, you might even need an attenuator to keep from overloading the TV tuner.
