Karl Palsness Hairpin circuit

@All

What about the bulb in the water and the difference in power from
top to bottom? Are these normal properties of RF?

Yes, it is.

The distance between no light and full light is 1/4 wavelength of the transmitted radio frequency.

The water is very high resistance at these frequencies.

A spark gap puts out a very wide band signal. The Lecher line acts as a tuned circuit.


Edit>>

The 1/4 wave measurement above is with the lamp connected from the shorting bar to another point on one vertical bar.

You can see a 1/2 wavelength the same way by connecting from one bar to another with the connections at the same vertical level.

Does anyone have information about that small part he puts on the table and it only spins in one direction?

Loner,

Thanks for your post, I know there's something unique to this circuit,
I just didn't have the technical terms to express it.

I found another replication of it, what this guy says sound like Chinese to
me, but maybe some of you guys can find it useful.

Adios.

    A Surfer can walk from the top of a wave into the trough.  The water through which the wave travels can not.
