Topband: "return" current - what is it?

[Yuri Blanarovich]

Sooo, there is no current and voltage variation along the standing wave 
resonant dipole?
Soooo, Jasik et al, all those antenna books, modeling programs showing 
RF CURRENT and/or RF VOLTAGE distribution along the (standing wave) 
solid antenna wire are thinking otherwise?
Like parallel LC circuit (say in amplifier) or RF choke doesn't have 
high RF voltage (low current) at one end and vice versa on the other 
end?
Hint: take the neon bulb and slide it along the RF radiator. On the 
resonant circuit you would see brightest light at the tip (hig voltage, 
low current) with brightness diminishing towards the feed point (dipole) 
or RF grounded end. The current is just opposite, lowest at the tip, 
highest at the feedpoint. IT VARIES along the length of even solid wire!
Applying Kirchoff to wrong case and arguing against reality is just 
misleading.
