The short question in all this is - can I run coax from 2 different
antennas into a splitter, then from the splitter to my TV, and get
signals from both antennas?

They're often called splitter-combiners, and there's a reason for
that.

Inside that mystery box is nothing more than 3, 5, or 7 wires
connected together. The shell of the splitter-combiner serves to
connect the outer shielding of the coax cable, and the center pins are
connected through these wires.
