antennas submerged in salt water work, how does that happen??


It was here about antennas made of salt water.
Is it a normal practice to make an underwater antennas?


yes, there are underwater antennas in use 24/7 by military

submarines... so how do the electrons get through the salt water?

The word electron does not appear on that page.

They don't. Radio waves travel through water the same way they travel
through outer space. Albeit better through water at ultra-low frequencies.

I don't see where you explained anything about the electrons. The
article doesn't, either.

I'll repeat the question in case you forgot it again.

"so how do the electrons get through the salt water?"

And of course then we have the problem of RF communications with people
who are in caves.

How do the electrons get through the dirt? Which seems to be even less
likely than salt water.

Having not read most of the nonsense that attends this kind of side
thread, I will dip my oar into this anyway and ask:

How do the electrons get through the air? (especially when, in their
ferocious struggle, they usually light up the night with corona in the
best of worst performance that rarely achieves propagation beyond an
inch).

Asymmetric molecule oscillations = sound waves.
Asymmetric electron oscillations = electric waves.

On that page are radio waves in air and water. Free electrons are
everywhere. But the freedom is material dependent.

In Nature are the continuous flows and the oscillatory flows.
The oscillatory flow is a second name of waves. If oscillations are
asymetric than net flow take place.

Electrons are everywhere. Their freedom is material dependent.

but then why can't i measure dc current from my antenna? and why do
my oscillations look so symmetric?

To measure it you must have an equipment and good will.
The last is more important.

Look at the original Hertz apparatus:
http://people.seas.harvard.edu/~jone...ertz/S_p11.gif

To have one portion of radiation it is enough to charge one half of the
dipole. Charging is made with DC.
After some time you can repeat it.

The radiation is in form of the damped wave:
http://en.wikipedia.org/wiki/File:Ondes_amorties.jpg

In damped waves each amplitude is smaller than the previous. So in one cycle
no symmetry.

It is obvious. But you can try to detect it.

can't detect it here, my waves look like perfectly symmetric sine
waves and i can not measure dc on antenna. how much dc should i have
with 1000w at 14mhz?
