I agree, Lou, but that is the case with "any" wire dipole mounted near the
ground to obtain reflection gain. His note implied that he had something
else in mind beyond the "gain" that any relatively low dipole will provide
compared to an outer-space situation.
So, I still have the question: what wire antennas did Rod have in mind to
provide gain, compared to a dipole mounted in the same location, that are
feasible for most folks to use and that would prompt him to advise the use
of "wire antennas?"
Joel in Maine gets by with his 40-meter wire beams but he has trees in the
right places and at the right heights, which most folk do not.
