He is not correct! Have you looked at the "piece" of wire - quarter wave antenna, having the max current at the base and ZERO at the tip? And voltage low at the base and high at the tip - corona? Wh

No, the original argument was: is the current at the ends of the loading coil (1/4 wave standing wave radiator) equal or is it diminishing at the top. The idea of "winding the antenna wire into the c
