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 ". So I look he http://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* |
