Default StrikeFinder Problem

Have you ever seen an arc welder when the ground lead isn't making good
contact? There is as much arcing at the ground clip as at the work rod.
Think of it as one continuous little tiny lightning bolt at close proximity
to the antenna. Since signals drop off as the square of the distance, and
figuring that the ground arc is about five or six feet (let's say six) from
the antenna and the Strikefinder has a range of somewhere around 200 miles,
we can say that the ratio of six feet to 200 miles is about 176,000:1.
176,000^2 is somewhere around 31 BILLION:1, so to produce a readable signal,
that arc only has to be one 31 billionth as strong as a lightning bolt which
ain't a difficult thing to do.

k?

It's either that or a ground somewhere. Why an iffy ground as culprit?
