I downloaded a couple of them, but I have a question. I opened them

formats. The loads did not import, but when I opened the same files
in EZNEC 3 I saw them as R+jX loads with only an 'X' value.

You can put in any R and XL value, Wes. The phase of the current will
not change. The magnitude decreases and the phase stays the same.

I learned from Dan, AC6LA, the author of MultiNEC, that some early
EZNEC versions save all loads as Laplace and he doesn't read those
into MultiNEC. Opening the files in EZNEC 3 and then just resaving
them makes the import into MultiNEC work okay, but this makes me
suspect that using your earlier files in my later version might be a
problem. The documentaion says otherwise though, but to be sure, what
are the actual load parameters.

Well, your Laplace files won't run on my EZNEC version 2.0. They all
come up as zeros. So I don't know what loads you used either.

I don't want to comment further until I know exactly what you are
using.

You can vary R and XL values from zero to infinity. The phase of the
current never changes. I tried values from 1+j300 to 1000+j300000
and it only affected the magnitude, not the phase.
