wave polarisation
"Szczepan Bialek" wrote in message ... So the most specific and important question is: How is frequency in receiving antenna. Is it doubled? no. i transmit a given frequency and that is what is received. easily measured even with simple instruments. |

But an antenna receive the doubled impulses (from the ends of the Hertz dipole). The simple instruments must distinguish the doubled frequency from the second harmonics. S* |

S* sure, they are double kicked... first one direction then the other within one cycle. you and art should get together, maybe he could straighten you out. |

So try to understand. The electrons (they have mass and inertia) colect in one end and next disappear. It is the one cycle. Next they travel to the other end. It takes time. So in space are send the two signals.(in one your cycle). In the same time 9Your cycle) the current flow to and fro. In unverified EM the current cause the spherical wave. In reality the ends. Only Your simple measurements can verify it. S* |

S* i have made my simple measurements, the frequency is not doubled by the antenna. You are to speedy. Look at the original Hertz experiment: http://people.seas.harvard.edu/~jone...Hertz_exp.html There is: "According to theory, if electromagnetic waves were spreading from the oscillator sparks, they would induce a current in the loop that would send sparks across the gap" In EM waves are produced by the current (oscllator sparks in the Hertz apparatus). One cycle is completed when the current flow to and fro. But there is possible the other theory. Electric waves are spreading from the ends (plates or big balls in Hertz apparatus). Now we know that electrons have mass and are compressible. So at the ends appear and disappear the huge charges. In that case an electric impulse is send when the current flows to (from one end) , and the next when the current flows fro (from the other end). So in one EM cycle are the two electric cycles. So the frequency is not doubled. The electric is twice more. Does your measurements distinguish radiation from the spakrks from that from the plates? S* |

There is: "According to theory, if electromagnetic waves were spreading from the oscillator sparks, they would induce a current in the loop that would send sparks across the gap" If? If is wrong. In EM waves are produced by the current (oscllator sparks in the Hertz apparatus). One cycle is completed when the current flow to and fro. You say this often, but it adds nothing important. But there is possible the other theory. Electric waves are spreading from the ends (plates or big balls in Hertz apparatus). This is not ANOTHER theory. Your first "If" is not a theory at all. It is an incorrect statement surrounded by poor writing. It is like this next statement: Now we know that electrons have mass and are compressible. Nonsense. So at the ends appear and disappear the huge charges. In that case an electric impulse is send when the current flows to (from one end) , and the next when the current flows fro (from the other end). Nonsense. So in one EM cycle are the two electric cycles. Nonsense. So the frequency is not doubled. The electric is twice more. This is either very poor English, or more nonsense. Does your measurements distinguish radiation from the spakrks from that from the plates? S* Of course they do. More the question: can you measure them too? If you cannot, then this explains the nonsense. 73's Richard Clark, KB7QHC |

S* I'm sorry, but i don't have a spark transmitter, those have been rather illegal for many years because of the extreme bandwidth and noise they generate. I use a nice clean sine wave so there is no harmonic generated. if you use a spark generator there will be many harmonics, but they come from the waveform being generated. |
