Karl Jan,
Can you share your program with us? This looks like an ideal way to deal
with both the 80 and 160M bands!
Thanks,

Hi Barry!
If you want to operate without a tuner, but with resonance at both
3.589MHz and 3.990MHz, you could add an additional dipole (with resonance
at 3.990MHz) 284mm apart from your "3.580MHz dipole". Just use som
spreathers and without any connection between the two elements, only the
one for the lowest frequency is to be feeded...
I made a small program to calculate the distance vs. resonance
frequencies, but I think I found the formulae for this in the ARRL Antenna
Handbook (don't remember the issue, but it was an old one!)
Best regards
