Gene,
My inverted L is at teh edge of my lawn. I have 35 radials in a 200 degress
radius in the wooded arear of my yard.
I add 6 more radials in the grassy area of my yard in November when finished
with the mowing and remove them in the spring. I measure the impedance before
and after. The resistance at resonanc goes down as I add the radials.
I will be interested in your measurements.
