some cosiderations

Ah I see you were looking at his most recent patent 7,221,164 and yeah that's pretty cutting edge allright. Who would of thought of using water as an E field sensor?

The previous patent I mentioned gives all the engineering details that are left out in the one you quoted plus the frequency graphs. And the distances above earth plus being able to see down 20,000 feet or greater definately puts it in the class of an LRL big time.

We of course recognize the fact that the E field is vertically polarized and so limits the distance for someone on the ground the possibility of that kind of range away from the target but still being able to get the depth no problem.
But how far can the vertically polarized E field be detected on the ground? What is the formula to calculate this?
