The field emisssion probably works in an antenna: "Field emission can happen from solid and liquid surfaces, or individual atoms into vacuum or open air," field emission is not likely at amateur power levels. " Transmitters for long and medium wave require good grounding and soil of high electrical conductivity. Locations at the sea or in river valleys are ideal, but the flood danger must be considered. Transmitters for UHF are best on high mountains to improve the range ". no they don't... those types of transmitters work just fine in airplanes with no soil available. So I look hehttp://en.wikipedia.org/wiki/Warsaw_radio_mast "This technique works by applying a DC ground at a point of minimum radiofrequency voltage, conducting static charge to ground without diminishing the radio energy. Static electrical charge can build up to high values, even at times of no thunderstorm activity, when such tall structures are insulated from ground." Would be interesting to know the value of the DC current. Do you agree that it is the field emission (loss of electrons)? S* loss of electrons maybe, but due to friction with particulates in the atmosphere. also partly due to the fair weather electric field: http://www.missioninstruments.com/pa...ec_fields.html |

He has yet to wonder how satellites could transmit very long. After all, there would come a point in time where the charge would be so high on the vacuum insulated satellite that it could perform his field emission any longer. It should be easy to observe as the signal strength would decrease with time. I haven't noticed that effect myself, nor has anyone else. tom K0TAR |

S* You know, he is sort of more amusing than Art. At first. Art can argue and Art makes no sense, and neither does Szechuan, but he can't build an argument that even sounds a little bit logical. And his arguments never change. Art makes up new stuff all the time. Prediction - Szechuan will eventually become so boring no one that no one will respond. tom K0TAR |

Each one of you can measure the DC ground current. Why you are so boring sending the same incontructive answer (no emission). Emission is a fact. It is interesting how it is much. S* |
