Speaking of texts, one of my co-workers gave me a wonderful paperback
textbook last week "The Theory and Design of Circular Antenna Arrays" by
James D. Tillman, Jr., The University of Tennessee Engineering
Experiment Station, 1966.

The design, testing, scope pictures and the wonderful racks of gear they
built makes for a great piece of work.

I have no idea why he had this book or where he got it, but am grateful
to get it.

Did it state that radiation was waves or particles and how he can
prove it ?
Is this in line with your extensive design of antennas?

No comments needed here.

What ever is the matter with you? You seem to want to pick a fight for
some reason.
So you are a qualified antenna engineer and you dislike my aproach to
antennas because I am a mechanical engineer or what. I experiment with
antennas which means I am not totally governed by the books and I
enjoy that. I also study so that my results can be understood
mathematically. Now I am not an antenna engineer but when you and
others
could not relate the mathematics of Gaussian statics to Maxwell I
realised that the so called gurus were not experts after all and this
was confirmed when the term equilibrium flumoxed all of you. Now you
claim efficiencies of some sort, does it show up on a receiver S
metre? I doubt it. And you claim 98% efficiency but supply zero
parameters.Heck, I can get a computer program to give me figures
better than that but it is meaningless
But all of this really doesn't matter on this newsgroup, I am not a
antenna engineer so in no way am I encroaching on the esteem you feel
you posses as a antenna engineer because of your electrical
background. Yes, you know more about antennas that is written in the
books, because you committed it to memory whether it was correct or
not to pass an exam. Feel better now?
