At 10 MHz, the electrons would vibrate back and forth at about 0.01 nanometer per 0.1 microsecond. Consider how large 0.01 nanometer really is so for all practical purposes, electrons don't flow at all at HF frequencies. Electrons at HF are just a bucket brigade for the photons that deliver the RF energy to the diode detector. Unless a circuit is at DC steady-state, photons are involved, i.e. RF involves photons which constitute the RF fields and RF waves. No matter how big the back and forth are.

By removing all reactance especially the magnetic field the current flow removed itself from the material and travels on the surface. This is not unusual as superconductors drop to zero resistance when the magnetic field is canceled or removed. There are only two resistances in radiation and if no skin depth is then generated then the material and its resistance is removed from Maxwell's equations Now one can question my understanding as to what is happening but the fact is my antenna swr does not go above 3:1 no matter what band I am on! Yes, by not understanding what is really happening it would be easy to say "dummy load " but that is not the real answer. So I would ask all what exactly is impossible about the sequence of event that I describe while adding that computer programs confirm it? By the way the antenna is sitting om the grass as height does not affect dish antennas! |

I know what the answer will be of course, an excuse why you can't have a Q with me or anyone else. tom K0TAR |

Wiki is more usefull than you: http://scitoys.com/scitoys/scitoys/r...ade_radio.html " Power from radio waves -- hooking up a meter to measure the voltage and current " "If you have a good antenna, or a strong radio station nearby, the ammeter might read more than 50 microamps. If you have a short antenna, you might get only 5 microamps and still be able to hear the station clearly in the headphones. I put up a 200 foot antenna between two trees over my house, and tuned to a 50,000 watt station about 30 miles away, and now I get 175 microamps of current through my meter." S* |

Yes, by not understanding what is really happening it would be easy to say "dummy load " but that is not the real answer. What would you consider the answer to be? It's really an inefficient toaster oven? So I would ask all what exactly is impossible about the sequence of event that I describe while adding that computer programs confirm it? You want the Bush or the Obama explanation? Lets ask both.. Hey Gee Dub, what do you think? "Son, your misapplication of the modeling programs have led you astray. Number one, you can't polish a turd into a diamond. Believe me, I've already tried it out at the Crawford ranch. Didn't pan out... Number two, the modeling programs are not coded to deal with turd polishing. So any results obtained from misapplying an antenna modeling program to simulate the performance of a polished turd is bound to end in frustration and gross error." Hey Barry, what's your angle? "I think we should give him a $500.000.00 grant!" I guess it was a split decision.. :/ By the way the antenna is sitting om the grass as height does not affect dish antennas! Actually, it does make it easier for the dog to drink the rain water out of it. Good call! |

The simplest radio: " Tape the other diode wire to a cold water faucet. This makes a good connection to the ground, and is thus called a 'ground' connection. Hold the remaining free bare wire of the earphone in your hand. This makes your body into the antenna for the radio. Put the earphone in your ear. If you are close to a strong AM radio station, you will be able to hear that station faintly in the earphone. You may hear more than one station at once. " The diode has the two ends. Which one should be tapped to a cold water faucet? S* |

S* well, of course, once you put a diode in the circuit you are forcing flow in only one direction. but try this, turn the diode around so it only allows electron flow FROM the ground... and you will still hear the station. so now how do electrons flowing from the remote antenna through the air get to ground through your diode?? |

In the opposite setup the wire is the antenna and your body is the chassis. Are you rich enough to check the simplest radio? Is the same power in the both arrangement? S* |
