Howdy:
In a j-pole the 1/4 wave element, and the bottom 1/4 of the 3/4
element should act as a transmission line, right? So... shouldn't these
elements be as very close to each other to cancel one another out, closer
than what I see on most j-poles? Or is this space have something to do
with the impedance of the antenna?
