Default Yagi efficiency

Well let me take you on a thinking journey OK? I will do it in stages
so there will be no reason to jump the gun with questions unless it is
pertinent to what I have said. Maybe a new thread would be better
before I start out on explaining new thoughts about antennas which are
away from the traditional designs which really requires an open mind
Look out for the Gaussian Antenna heading and we will get started. You
can read up on Gaussian antennas under Google in the mean time to get
up to speed.The wife just got out of hospital so bear with me as I am
having to do different things

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.
