Hi Richard,

I think what you're seeing is the 3-D interference pattern generated
by your sources. I'm not sure that really tells us very much about
the antennas themselves. You'd need to surround each of the antennas
with a uniform field in order to compare them. By uniform, I mean the
field intensity toward the antenna is the same in any direction.


How about polarization?

Hi Roy,

Your guess is better than mine. I think in order not to bias the
results, the solution would have to be that each source is randomly
polarized, i.e. the Sun redshifted down into the radio spectrum - coming
from every direction. The ring of point sources is an interesting
approach. One could use rings at some number of elevation angles, both
above and below the plane of the antennas. The greater the elevation
angle, the smaller the diameter of the ring such that the radial
distance to the antenna is kept constant. But I imgaine you have ideas
of your own in this regard.
