Re: LF: Unusual radio mast video Ukraine ??

Mark,

       I don't know what the power of the system is but I suspect that since at the base of 1/4 wave antenna the voltage is lowest this might be running substantial power. Also note that they are drawing arcs with grass, not metal or a graphite pencil. Very likely that they would have been killed if they had used a metal spike to draw the arc or if they had been standing on damp ground etc.

The antenna in the  Ukrainian video looks to be quite a low power system.

If you try that on a high power system  you would suffer serious injury or even death.

The arcs drawn in the video were a few mm long. I have seen arcs from high power systems over 6" long  and some considerably longer.  Once an arc starts it can self sustain, even bypassing the path that started it..

 if you became part of the path to earth things would vaporise quickly, including parts of you.

 These systems are very dangerous.  Don't try this at home (or on a local radio transmitter site)

 

You have been warned.
