But you know that the antenna must be tunned. Probably the field emission

starts after tunning.
It would be interesting to measure the voltage pikes on the tip of CB whip
before and after tunning.

If the voltage pikes are asymmetric than the field emissin/absorption
also

and we have Stokes drift.

How to mesure Stokes drift - it is a question.


i have measured the voltage at the tip of an antenna, it is a nice

sine wave, no spikes.

How many volts is before tunnig and after.

we don't use spark gap any more if you haven't

noticed, modern radios use nice symmetric sine wave circuits. if we
didn't have nice sine waves there would be harmonics that would
interfere with other bands. your distorted waves would be horrible in
today's world. look up specifications for distortion in radio
transmitters and then go study fourier transforms to see the effects
of distortion on the spectrum of the signal.

It seems that distortion is very small.

i am bored, you have no

new theories like art does, you just keep picking random unrelated
facts, so this just isn't fun any more.

I am tired also. I come back whan I find "How to measure Stokes drift"
Best Regards,
Szczepan
