Default Yagi efficiency

I figure that if it works ok on my program AO PRO and it is then
checked out OK on NEC4
independently,and I can produce the electrical laws that backs it up it
will get into the books tho for the present time it is not there now.
For a very long time I have tried to introduce this and others to those
who are experienced in that sort of thing but I could never get it off
the ground because the thread kept on being changed to suit somebodies
whim or it developed into a name calling setup that it was impossible
to procede. Actually I let one patent application drop during the
examination process because of the badmouthing that I got but my back
is now stiffer and this one is going all the way. I do it not for money
reasons but because antennas is my hobby despite my so called lack of
knoweledge I have had patents during my working years at G.E. and other
places so the idea of patents doesn't carry much with me any more. For
all the experts we have had over the years on this newsgroup I have
never been able to thrash out one of my ideas to fruition because of
various nebulous reasons. If I brought one up involving SWR, coupling,
baluns e.t.c. the thread will grow by leaps and bounds in minuits
because everybody has something to say about it. If a subject is
brought up that one cannot provide insight then that person feels
denied that he cant post so he will resort to firing bullets and
stones.

If you refer to something that is "not in the books" one should take
great care. Why I do think evidence can be brought out and can be
demonstrated that some of the ways we "think" antennas are working is
not real, however, great men have developed thinking models and formulas
which are able to let us design and use WORKING antennas which are
PRACTICAL. I site that mysterious 377 ohms as an example, or for
another, incorporating the spin rate of the earth into antenna formulas
(time), ridiculous (but useful!) But, those "old books" contain methods
and means to develop antennas which do work and which do work well, we
owe much to those who have gone before us ...

I am only hoping that by refusing to allow "magic numbers" to be
embedded into equations without any suitable explanation of what those
numbers are "REALLY ABOUT" will one day awake the man who can form the
vision and see what the others have all been unable to, Tesla seemed to
have had an excellent ability which I hold as example of the type of
"vision seer" I mean.

I have an open mind, I guess you are as likely as the next guy to "be
the one!" Never hurts to try anyway ...

However, thank God practical antennas work and we have the tools to
design and build them.
