There has been some vigorous debate lately about the advantages
and disadvantages of big and small antennas, with some holding
the view that big antennas have superior radiation patterns to small
ones, and some holding the opposite is true. The aim of the
experiment is to put this to a practical test.
I don't recall that the debate was principally about radiation patterns of
big versus small antennas, as such. Even a 100m mast is electrically small
at these frequencies, and would have no different pattern from a 10m mast.
It appears that what you will actually be testing is the difference in
radiation patterns between an exclusively vertical radiator and one with a
significant horizontal component, is it not?
The idea is to set the antenna currents so that the same
effective radiated power should be obtained from both antennas,
and then see how signal strengths compare.
How will you be determining effective radiated power? Isn't ERP pretty much
_defined_ in terms of field strength?
