David are you going nuts? I used the word impedance whichcan mean two
components only one of which is used for power. What on earth are you
trying to say now or are you looking for a reason to thro stones. Now
calm down and point out where I was not CORRECT as you put it and what
are the consequences of this error relative to what we are talking
about?
If your point is that I didn't emphasise the word complex then there is
no need to respond, you can have it your way I don't mind if it helps
you out with your apparent anger.

Help me help me please , a detuned element has a reactive impedance

NOT CORRECT! It is a complex impedance that contains both a resistive and an
reactive component.

Now with your superior knowledge and education show not just me but all
of us how the production of a reactive impedance does not or cannot
impede the formation of emmited flux? I dont want just comments or
guesses just an explanation of your position which aligns with the laws
of Kirchoff, Ampere, Green ,Laplace etc as a group or as single people
to give your response some credability . Cecil has given you a starting
point as to what exactly reactance is so the rest should be easy for
you considering how easily you can dismiss my logic and education
regarding the Yagi antenna. Bill I cant wait to hear the mutterings of
a master of your station, a chance to learn something really new, maybe
not even written in a book Go man go! Well I know you can't.... but I
am just demonstrating that if you want to snipe then others will be
encouraged to snipe and it is not nice. Knoweledge is what I am after
not errent gun shots

Since two elements out of the
three are producing reactive impedances and wherein
the reactive portions of impedance is pure waste
pray tell me how one can consider a yagi as efficient?

Please let us know what electronics school you attended so we can
