Insulation diameter vs Impedance OR how to get 20dBi out of a short Dipole

Surely it is your model that is an aberration. Did it include such things as
the loss tangent of the dielectric and the effects of the resistivity of the
liquid ?
Hi Jeff,
An aberration was already included in the list of possible outcomes. I
did not include such things as you suggest because there was no
mechanism to. However, de-ionized water is not that hard to come by,
but would certainly lose that characteristic quickly. As de-ionized
(and further treated) water has none of the defects you anticipate, I
certainly didn't lose sleep in the prospects of its use in HF.
Further, I do have access to a bulk of work employing water loaded
antennas (peer reviewed and not just more vanity publishing) that can
be used to test reality against theory (as corrupted as it may be by
the aberration factor).
