Topband: modeling BOGs (or whatever we call them)

[Mike Waters]

Hi Jerry,

Thanks for sharing this. But I thought that it was a well-established fact
that NO antenna modeling software does well with antennas close to the
ground.

Modeling ground loss or wires close to the earth is a challenge, to put it
mildly.
