Again I question: "The ground system is simply not long enough to provide a 
low impedance return for much of the antenna current"

When I look at my own numbers from previous posts on the subject I believe 
the typical backyard system may only be capable of returning about 60% of 
the maximum possible current (the AC resistance of the loading coil being 
the only AC resistance in the circuit for max case). The reason for the 40% 
loss is probably is not the length of the radials but the dielectric 
properties of the gnd system. So I guess we aren't that far apart on this. 
Don't get me going on this cuz I'm likely to spend my lifes savings on a 
piece of clear land just for finding out the answer. <G>

TGIF!
