With no time invested and no pretense of knowledge...
Considering the considerable vertical separation of the antennae in question
and the considerable range of arrival angles, is it reasonable to think there
is one answer to this question?
With the phase effect of these factors increasing with increasing frequency,
more scatter would be expected.
I have a long standing pipedream of building a few phase shifter boxes and
using them to feed multiple amplifiers, feeding multiple radiators, to optimize
performance in a desired direction. A small increment version of the boxes
used with four squares. Sounds a lot like phased array RADAR and SONAR, doesn't
it.
I have lots of 4-125A tubes and power transformers, if anyone wants to do it.
