Dumb question: how do you reduce noise without reducing the strength
of the signals you want to hear? How does the antenna know which is
which?

Beams seem to "know" how to receive a signal from one direction while
ignoring noise from the opposite direction. My horizontal dipole seems
to "know" how to ignore vertically polarized noise.
