Hi, Jim.
Assuming this is a homebrew design, if you can accurately describe the
physical dimensions I'll try to model it for you:
1. length and taper of the elements
2. diameter of the elements
3. Location of the capacity hats and a complete description of what
they look like.
If the compressible coils are right at the feedpoint and on either side
of it I don't need their dimensions ... I can just choose an inductance
that makes the antenna resonant.

When a 1/2 sized loaded 75m rotary dipole (combo of Capacity hats part
way out either side + a seco systems compressible coils at the
feedpoint)..... what is the FS ratio... when modeled in free space ?? (
68' log ele...tip to tip)
This is more academic than anything. Right now, I have no way to model
that config.
