I agree a good ground 30 feet up is much better in the face
of local clutter, and that a ground system isn't really
elevated until it is up a good fraction of a wavelength, but
I don't understand the minimum 2000 feet of wire.
20-30 radials 40-50 ft long would be within a fraction of a
dB of a perfect ground on 80 through ten meters, and people
can compromise a bit less than that and not notice it.
I use 100 radials on the 200ft tower I use on 160 but that
was largely overkill. The gain flattens out here at about 30
radials on 80 and 40 meters, and about 40 radials on 160.
