eddie, im talking about the tip of the antenna,

by imax i mean current maxima 1/4wave from the tip,

you may have more luck with the arrl open sleeve design as it uses equal diameter conductors and a parallel sleeve which nec can handle, the downside is its not exactly a sigma,

id be guessing if i said any particular length due to the variables, i don't even know if the length that worked best here is longer than it should be.
