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? http://www.qsl.net/vk5br/UwaterComms.htm S* |

Radio waves travel through water the same way they travel through outer space. Albeit better through water at ultra-low frequencies. http://www.qsl.net/vk5br/UwaterComms.htm S* The word electron does not appear on that page. |

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. tom K0TAR |

How do the electrons get through the dirt? 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). 73's Richard Clark, KB7QHC |

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. S* |

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.

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. S* |

S* 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? |
