I didn't say what I wanted to say in my last reply to this
posting so I canceled my first reply and am substituting
this one for it. It the older reply made it off my server,
please ignore it.

You obviously misunderstood what I said. I didn't say the charge
equalized between the charged particle and the wire. What I said
is after the charge is deposited on the wire and the particle
that did the depositing of the charge is long gone, the charge
deposited by that particle will equalize between two identical
dipole elements that are link coupled.

Let's say we have a perfectly symmetrical link-coupled dipole
and we deposit one coulomb on one element. Please explain the
laws of physics that prohibit those two dipole elements from
equalizing at the same charge.

Substitute "corona" for China and "charged particle

Typical of Cecil Moore. Do you think you are the center of attention
and no one else is worth talking to? I wasn't even talking to you!

Look back Cecil. K0TAR said there couldn't be corona in the rain.
That's incorrect.

Speak when spoken to Cecil.

Hang on, I didn't say "couldn't", I said I doubted it, and I also said I
was asking a question. And you and others have given lots of
information since, thank you.

I not convinced that corona is what I'm hearing, but I'm no longer
convinced it's not, either.

That's good. You shouldn't be convinced. Especially if it is something
just accepted and circulated without experimental results confirming
it.

There are a lot of odd ideas that are deeply rooted, especially when it
comes to electric fields, noise, and charges.

Look at the shielded loop thread that just went on! Someone started a
whole thread just to show the shield blocked electric fields and
"noise", when all the shield really does is help balance the antenna
and eleimnate common mode responses.

The "dc path eliminates noise" and the "noise comes from each particle
hitting the antenna and a dc path reduces it" are nearly as far
fetched.

The potential difference is between the earth and space above the
earth. Clouds can also become "charged" and have a large potential
difference to earth and anything connected to earth, especially in bad
weather. That's why the world has lightning hits!

Anything connected to earth and sticking up and out in the air will
have a huge potential difference between it and anything in the space
around it at the same height or higher.

The sharper, higher, and more extended the conductive protrusions are
the worse the problem is, and the best ground connection in the world
won't reduce it (it can actually only make it worse). Rain or snow or
dust won't make the problem less either. Neither will high humidity.

I spent a lot of time and money trying to fix what I thought was the
problem (the particles making noise) until I learned the folklore was
wrong.

I already explained that to you, Tom. Perhaps you missed it.
In the following diagrams, CH is the charge transferred to
the antenna by a charged particle or any other means.

Given a non-folded dipole, any equalizing of the charge between
the two identical dipole elements must flow through the link
where the noise is picked up by the receiver.

-------CH------+ +---------------
| |
/ /
| |
Link to
receiver

Turning the non-folded dipole into a folded dipole provides
a *local DC path* between the two elements. Most of the
noise will follow that DC path between elements instead of
traveling down the transmission line, through the link, and
back up the transmission line. Hint: Ohm's law.

DC path between elements
+-------------------------------+
+-------CH-----+ +--------------+
| |
/ /
| |
Link to
Receiver

You avoided replying to this last time. One wonders why.
Please explain why you think the charge on the folded dipole
would not take the DC path of least resistance.

There really wasn't any good way to answer an idea so fatally flawed. I
ignored it thinking you would figure it out on your own later, or that
Yuri would help you get a different perspective on things.

By the way Cecil, I'm absolutely serious.

I was very surprised you didn't think through what you drew and what
you proposed before posting it.

I expected even Yuri would catch the mistake you made and correct you.
