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. 73, Mike www.w0btu.com On Sat, May 14, 2016 at

I sent this message to K9LA, then it occurred to me that maybe I should sent it to the group also. So here it is. I agree that BOGs are not well understood. What started this whole process of comparison of measured data to NEC predictions was the fact that with simulations I found a way of
