David,

Bill, W4ZV referenced this effect early in the discussion:

"This problem has to do with something called magnetic coupling
(or polarization) loss.  This primarily affects 160m which is closest to
the gyro-electron frequency which varies from about 0.7-1.7 MHz worldwide
depending on the intensity of the magnetic field)."
