I did get it to model SWR with high reactances(to me anyways).
Does this seem right? I dunno. Thanks


Hi Bill,

At this point, you need to provide more specifics. One, what
frequencies? Two, did they match your experience with a physical
model?

To answer your question lacking this information, yes this seems right
- at least somewhere in the panorama of all possible outcomes. It
stands to reason that ANY antenna, when looked at across a wide enough
spectrum, will reveal both resonances and high reactances, and many
combinations in between. This is just par for the course.

Now, if you find you are experiencing these high reactances in nature
as well as in modeling; then try one thing: Break the wire at a point
that is on the opposite side of the loop from the feedpoint and see
what happens.
