[Elecraft] Antenna Separation for Diversity

[Guy Olinger K2AV]

Given that the vertical has low or ground radials, and the dipole is
up a quarter wave or more, the vertical antenna off the end of a
dipole on the same band will have a lot of energy coupled from the
dipole.  It is not intuitive until one has gotten used to it.   This
is easy to model to see the kind of coupling that takes place.
