Tim,
You were obviously going for best high angle *RX* capability, which
requires attenuation of all low angle (i.e. static) reception. Truly a
specialized antenna.

Hello Wilson:
Each radial (6) is 95 feet long. There are two that are directly under the two
sides of the dipole the other four start out at the feedpoint of the dipole and
the ends are 3 feet apart with respect to the ones that are directly below the
dipole.
I used this low height (20 feet flat) resonant dipole antenna for a long time
without the radials on the ground and it worked great (NVIS). I think it works
better with the radials - but not night and day better.
There was a question about my S0 noise level. That is a result of no switching
supplies in the shack or house and working with the power company and neighbors
to eliminate all man made noise sources. Also correctly grounding and bonding
antennas, towers and shack components. Lots of ferrite in the right places. And
a few visits from K3RFI!

Hi Tim,
What's the orientation of the "radials"?
Are they maybe parallel to the antenna? Cut to be reflectors?
Have you compared that antenna to a higher dipole in about the same orientation?
I'm sure going to listen for it.
