P.S. I have been some discussions that the
antennas need to be wavelengths apart,
but I think that is when you are trying
to copy a single station and want the
second antenna to deal with QSB and path
differences, and wide separation is
probably an advantage there.
Perhaps what I'm doing would be better
described as "directional" diversity.
Although you have some "directional" diversity for a signal
whose azimuthal angle is varying, your situation is normally
referred to as polarization diversity. What is most
common, especially under band-opening and band-closing
conditions, is for the polarization to rotate and having
separate vertical and horizontal arrays can reduce the
associated QSB.
