Other than getting into the Guinness Book of World Records, one has to
wonder why anyone would bother with such a project. It's the old story
of the more gain you have, the narrower the beamwidth. This guy is
probably going to miss more DX than he hears.
But it's an interesting story, no doubt about that.
