[DX] Re: uusi aika,uudet kujeet ? - Sähköä ilmassa...



Hei!

 

Lienee syytä noudattaa äärimmäistä varovaisuutta pallo- ja leija-antennien kanssa. Juttua löytyy näiltäkin kulmilta…

 

“The danger arises from the electric field between the earth and ionosphere. This field is about one hundred volts per meter (in the vertical direction), and is always present. Any antenna launched into the clear blue yonder will aquire a charge large enough to wipe out a final transistor, or a receiver front end.”

 

” My friend Tony, was practically thrown across the deck of his boat when he touched the ungrounded wire on one of our kite- antenna experiments.”
