Certainly not elaborate at this point. Many, many short - 30 ft to 50 foot
radials of #12 plastic covered household wire. Two radials are over
100 feet, running along back of my - and neighbors backyards. One is tied
to a chain link fence. All are terminated with 3 ft copper pipe.
If anyone ever digs up this yard for gardening, they will find over
30 years of various radial systems. Great project for an archaeologist
during another century !
Will get a bridge on it shortly and see just what it really looks like, but
I have added 500 uH is series with the "uplink" and all the theoretical
calculations fall right in place with the actual frequency resonant points.
Still looks like 380 pF for the top-hat. Looks like 3.55 uH at maximum now.
