I am focusing on the issue of power transfer at the junction of the line and
the antenna. Specifically, in a multiband dipole where the figures (all of
them) will vary wildly from band to band. Maximum power transfers at
resonance (oh no, let's not get into a war defining that). But I think it
is safe to say by anyone's definition, a multiband dipole usually not
operated at it's resonant frequencies. If the line is 450 ohm and the
antenna is 2 ohm or 20 ohm or 2000 ohm, there is not resonance.
Intuitively, I have got to think a 200:1 mismatch is significant.

So what is the loss at the antenna/line junction? I understand matching at
the transmitter end. I understand using low loss line. I don't understand
why the mismatch at the antenna junction is ignored.
