Could the coupling with the ether from the antenna conductors be less efficient so the RF naturally.. stays on the outside surface of this nice easy electron rich conductor and coax ? Just throwing a thought out there.


The GIF makes some sense now, clearly a parallel tuned circuit following through to an antenna (and an antenna being part of a tuned circuit coupled to its surroundings including ground in the reactive near field). I was reading that in this reactive near field taken to be 1/2 wavelength approx the system behaves like a lumped capacitor storing energy. (and losing energy in the earth below). And the earth is like a lossy capacitor. It seems the dipole elements appear as capacitive elements. And at resonance at the correct frequency electromagnetic waves are efficiently emitted into space/gasses around.


Diagrams are very helpful... it is like revision.. and supplementation. Surprising how fast the basics vacate the brain once you pass an exam and start making contacts.
