This is completely wrong. In a _linear_ systems adding two signals
cannot create new frequencies, including doubling. In the frequency
domain this is clear. If you look in the time domain and look at zero
crossings you may be confused. Do the math for the addition of two
sine waves of different phase.

In reality no sine waves.

The you had better learn what Fourier analysis is all about.

In the ends of a dipole the voltage is doubled
(VSWR) and the strong picks are radiated.

Stop relying on internet images you don't understand and may not have
any relevance to the discussion.

Discussion is on the harmonics. The dipoles can produce the frequency
doubling.

If that were true radio communications would be much more of a mess than
it currently is. You don't understand antennas and need to start learning.



You can do the math in the time domain, or frequency domain. Either
should tell you there is no doubling of frequencies.

In the school math the water waves are transversal. Look as they are
like: http://en.wikipedia.org/wiki/Stokes_drift

In order to generate new frequencies you need to have a non-linear
effect. Addition is NOT a non-linear operation.

The two picks from the ends of the dipole are not linear.

How would you go about proving that?

Joe, he's either a troll or an idiot. It matters little which.
Reasoning with him is fruitless, and he lives in a world where he makes
up his own facts, similar to Art, so facts won't work either.

He's been trolling here off and on for a few months. Most of his posts
run on about the same couple themes.

Real waves are not symetrical. They are like the solitons:

The mess was in 1930. Remedy was applied.

I am not able to measure the shape of the picks.
You all can.
You can also check the "addition of two" picks (solitons).
