If you obtain a normal toroid type transformer with say 6 connections
(female connection)
for various so called standard ratios you can connect these to a rotary
switch which then allows you
to obtain multiple ratios over and above those listed on the transformer.
One of these at the top of the tower and driven by a stepping motor should
cover all your needs.

I would like to build baluns with non-conventional ratios, and am sure
I have seen something in HAM RADIO.

Jerry Sevick's (W2FMI) books contain some information on
odd ratio transmission line transformers. I think they are
available from the ARRL.
