Galvanized or Copper Gound Rods?

It is interesting how it is much. first, the fcc would get really mad at me if my rf waves weren't symmetric, that would make for horribly distorted signals! Each waves transports mass in direction from the source. This is form of asymmetry. and yes, i have measured the dc ground current and it is also zero. when you have a transmitter in your car are the rubber tires not isolating the car body from ground? You do not read my posts: ""The use of the term ground (or earth) is so common in electrical and electronics applications that circuits in portable electronic devices such as cell phones and media players as well as circuits in vehicles such as ships, aircraft, and spacecraft may be spoken of as having a "ground" connection without any actual connection to the Earth. This is usually a large conductor attached to one side of the power supply (such as the "ground plane" on a printed circuit board) which serves as the common return path for current from many different components in the circuit." do you get shocked after you have been transmitting for a while and step out of your car? It is common event. where does the ground current go when you have a plastic cased handheld radio? To chassis. See the chassis ground. i agree, mr. b is not as much fun as art... at least he made up things that weren't so easy to observe as wrong, after all who could see the waste deep levitating neutrinos jumping off their diamagnetic antennas. mr. b's stuff is just absurd. Radio was made by Stokes, Helmholtz and Tesla. I try to remember it to you. S* |

Before that Tesla did a little (from: http://en.wikipedia.org/wiki/Nikola_Tesla ): "Tesla's patents and theoretical work formed the basis of modern alternating current (AC) electric power systems, including the polyphase system of electrical distribution and the AC motor, which helped usher in the Second Industrial Revolution." Yep, before Tesla went senile he did some stuff, but you have never done anything before going senile. In the radio area it is nothing to do. Everything was done by Stokes, Helmholtz and Tesla. Radio people should know a little about them. The first step should be measuring the DC ground current. S* |

Your mistake here is to assume that because they can sink current that the are sinking DC current. The "ground", as you like to think about it may carry current during the RF cycle, but there is nothing that would cause an unbalanced charge buildup since it IS symmetrical. Your mistake here is to assume that the RF cycle, IS symmetrical. Each real wave is asymmetrical. The forward pulse is always stronger than the return. For this reason you must have power on. S* Incorrect. tom K0TAR |

S* that quote is correct... unfortunately the voltages created by most radio transmitters aren't high enough to overcome the metal work function so no field emission takes place from antennas. and even if it did it wouldn't go anywhere because radio waves are symmetric. |
