Welcome to the forum.
You have a good selection of very strong signals, all in about the same direction.
The C2V is a good choice, aimed at 117 degrees magnetic, but there are three unknowns in your situation.
The first is the signal loss from putting the antenna in the attic. You should be OK, but stucco, aluminum siding, or aluminum radiant barrier will block the signals.
It might be necessary to try different locations in the attic.
The second unknown is the wiring that is already in place. You don't really know what is inside the walls that might give you a problem, unless you did the wiring.
The third is the very strong FM signals in your area that might need an FM trap to protect real channels 7 and 13 from interference.
I don't need to tell you to scan for antenna channels, not cable channels, do I?
