As you see in the radials are many ends. There is the lower voltage and

almost no radiation (electron loss). Radial work like the receiver antena
(caught electrons from air)


Without the radials your stations can work only in a "salt-water swamp".


yes, but how does the electron in a single radial know it is at the


end of a radial and not double

In each end the voltage has tendency to be doubled (standing wave). If you
have radials and the LED you can measure the voltage. It will be lower in 10
radials than in 6.


oh, so it does double at the end of a radial.. that is different from
what you said earlier.


as opposed to the electron at the end


of an antenna that does double??

You know what to do to have low VSWR. Low VSWR means that the voltage is so
high that the intensive emission of electrons take place.

*At higher voltage the emission or sparks make low VSWR.

oh, so the swr changes with transmitter power? that is an observable
prediction that is obviously false... go back to square 1 and start
your theory over again.
