Perhaps you're remembering a restriction with MININEC-based programs,
which had problems with close spaced parallel wires.
I apologize. I think I mentioned that your program had limitations
that would not allow me to model what I wanted, which in my case is
close parallel elements. I was pretty sure that was why I quit using
it. Maybe there was another reason.
Whatever the case, I have, and still do, appreciate hearing your
knowledge and information.
It isn't my desire to design a new earth-shattering antenna or to
super-fine tune a yagi, but to use the rules of thumb in antennas to
build antennas with specific purposes in mind such as for portability,
maximum number of HF bands with minimal losses, and maximum gain with
minimum cost.
I gave up on an all-band HF antenna. there are just too many bands
these days. I built one from 80 - 6 meters in parallel dipole format.
It became such a bear to handle that it wasn't worth the effort trying
to keep it untangled, not to mention the weight of it.
I guess I digress.
