Default Length & number of radials again

Perhaps some kind person who has been able to afford the latest issue

- when fed against a ground system of 50 uniformly distributed radial
wires, each 1.64mm in diameter (14 AWG) buried to a depth of 25mm (1
inch), of length 10 metres -


Would it help to model this in EZNEC with the radials 1/1000
of a wavelength above ground?

Just heard a funny line on Stargate SG-1 on TV:
"This planet is as dead as a Texas salad bar."
