Hi Jolyon,

I'm not sure I understand. Could you elaborate (how's your ascii art?).
Do you mean mounting a helical primary
"below" the bottom turn of the secondary? If this is the case, I would
expect a rather "low" couping. If you haven't
run ACMI before, you might want to model your idea in ACMI to take a
look at such parameters.

The following link discusses the program and provides a link for the
program download.

Take care,
Bart
