Sure, the article was called, "Everything Works," and was by Tom Schiller,
N6BT, the proprietor of Force-12.
I've experienced some similar stuff over the years, which help clarify that
the difference between an average antenna an an astonishingly excellent one
for the same frequency can be so vast that most wouldn't actually believe
it. Like 40-50-60 dB difference. On HF, not microwaves. It truly is
amazing when you get to operate using antennas like that. -WB2WIK/6
