So in finishing up, a horizontal loop probably offers little noise
immunity when operated in the countryside where you have no nearby
sources of interference.

A loop antenna reduces one type of noise considerably compared to a dipole, i.e. precipitation static which is unrelated to EM far-field signals.

If you ground your dipole properly, you have less static.
Commercial dipole antennas also are shielded for that reason.
Ever seen one?
