[TowerTalk] Guy wire interaction - the devil is in the details (score: 1): Author: W8JI@contesting.com (Tom Rauch); Date: Sat, 10 Apr 1999 07:40:34 -0400; Hi Guy, Measuring "big things" is always a royal pain. There is often as much self-capacitance and stray capacitance as "across the component" capacitance. It isn't like measuring a 10 pF ceramic dis; /archives//html/Towertalk/1999-04/msg00206.html (10,315 bytes)

Dippers may be a pain, but they certainly can confirm the [octave, order of magnitude, general neighborhood, approximate value] of a capacitor or inductor.

Virtually ALL charts ignore capacitance across the strain insulators, and the self-capacitance of the loop ends. Because of that, most non-resonant lengths listed are somewhat; /archives//html/Towertalk/1999-04/msg00155.html (9,311 bytes)

There is no "impedance match" between a high-Z end in an area dominated by the antenna's current.
