Hello all Voltas.
Under a Title... RF down a plastic spindle.
Dem, G0TSU, has suggested....
" It's induced - the vanes have a very high voltage on them,
lets call this a primary.
Your little grub screw is now a secondary.
Even the smallest amount of "turns" coupled with
such a high voltage will still give quite a charge"
Comment...
I would say it's likely to be 'capacitive'!
The "induced" voltage would be due to a charge on one electrode of a
capacitor inducing an opposite charge on the other electrode.
A comment from Eddie, G3ZJO, is right on the button!
"Hmm, someone has fitted the shaft the wrong way round. Re fit with the
knob on the Negative Phase end and the RF will flow back in instead of
out."
Yes Eddie, but at RF I think your 'polarity' would have you upside-down. :-)
73. Dick. VK3ABK. (Not the best joke we have heard in 2005. But maybe 2006 ?)
