Hi Antonio,
you can top load an antenna with an isotropic capacity, or you can bottom
load it
with an inductance. Either way, it's the long metal conductor that radiates TEM
waves 1/2 a wave length from it. With a TC there is no radiation zone (not
much of
one anyway), this is because there is very little radiation resistance. The net
result is that the E and H field can't get in phase, this results in only a
near-field where the E and H fields stay 90 degrees out of phase. I guess
this is
the electromagnetic version of reactive power, TEM being the real power.
Perhaps
this is what scalar waves are, the E and H field being 90 degrees out of phase,
the reactive radiation :)

Gavin, U.K.
