Andy, Terry...
"Check out this web page
http://www.djmelectronics.com/articles/emc-antenna-parameters-p3.html
which has a detailed discussion of antenna factor. Note that their
definition of antenna factor (AF) is the reciprocal of yours (which
they define as the "effective length", h-sub-e)."
If that doesn't give one a sense of clarity drowned in unmanageable
specificity......
Without excruciating attention to detail in the close environment, and out in
an uncluttered antenna range, it is nearly impossible to get these formulas to
show up in actual measurements beyond "rough correspondence" in orders of
magnitude.
Beyond that, for mere mortals, in terms of actual usefulness hearing stuff at
the home station with all the miscellaneous conductors and noise around, all
that one can sometimes say is that "I could hear him on one antenna and not as
well on the other."
73, Guy.
