Do it on 28MHz, and you can calculate pretty accurately the figures for the
lower bands: the trim up if needed.

Starts to take away the advantage of g-g zero bias, though, doesn't it? best
is to feed from a tetrode, which has a relatively high resistance: that was
why there was a magic length of cable for the 30S1 apparently: the input
networks plus cable length plus the pi tank in the 32S1 was a whole number
of half wavelengths on each band - according to Pappenfus et al, anyway. And
they should know.
