During the T/A tests last winter I ran out 2 additional radials 150 ft. long  into the sea water with 4ft long earth rods. Recently the grass had to be cut so I brought these radial in,carefully checking the Ant. current with and without the radials. NO DIFF!This brought me back to the" wire in the air theory" and I did somthing that I have been planning for some time. I added an extra 180 ft in the zig-zag configuration,in spite of the fact that Eznec recons that my top load is long enough to have linear current in the vert. section,and  no improvement to be gained from the additional wire in the air.(Rad. res. only increasing from 0.069-0.070ohms).   But Eznec doesnt adequately simulate currents in the ground at these frequencies. So I checked the Ant. current before and after. Before 3.2A after 3.7 Amps!!!Very worth while,and once again "Wire in the Air" is vastly superior to wire in the ground.,at my location at least. My 350mwERP is now 450mw ERP.Antenna now  48ft high,
Think of what could be achieved from those with 100 feet plus, vertical antennas top loaded with inverted L's top section of 300 feet or more or other configurations covering several acres of real estate.
There are plenty of radio amateurs suitably equipped with the hardware and proficient at high speed cw but not INTERESTED - watch out !!!!!!!!!!!!!!

vert section 42ft from top of loading coil. Horizontal top 650 ft (apart from last 180 ft which slopes to 40 ft.Top wires in zig zag config.  73s Laurie.
