" wrote about Richard Harrison's post:
Richard, it is now quite clear that you were not undertaking a test
referenced to a dipole. All you were doing is confirming a target area
under average conditions to ensure the language used was compatable
to the target area.....Period
More important to me is your statement that :

" Propagation dictates the take off angle that the signal actually
follows regardless of what your antennas do"
_________

Your arguments arise from trying to compare two different test goals, e.g.,
accurately measuring the free space az/el radiation patterns of an antenna
itself, versus how those radiation patterns may perform in a particular
application (height above ground, ground characteristics, ionospheric
propagation characteristics, reflection sources, target coverage zone, etc).

Classic antenna test ranges are designed to measure the az/el radiation
patterns of antennas themselves, independent of their environment. What
that radiation will provide in terms of a desired "coverage" result is
another matter, and is the responsibility of the RF system designer -- not
the antenna test range.
