I noted no acceleration nor motion. As a firm believer in the
conservation of energy I`m sure that the antenna, on average, received
no more energy than it emitted or conducted away. That is balance or
equilibrium.

Yes, and he also mentions the Yagi array. But I believe Terman meant to
say the best antenna gains of the day, for the antenna`s size,
regardless of direct or parasitic drive, were obtained from corner
reflector and Yagi antennas. That hasn`t changed but it certainly may.
But, Kraus, whose invention, the W8JK array, has two dipole elements
spaced 0.125 wavelengths apart and driven 180-degrees out of phase,
certainly has no parasitic element. That was certainly on his mind when
he wrote the comments on page 185 in "Antennas". On the facing page,
184, he diagrams two antennas, the W8JK and a stack of two dipoles which
are driven in-phase, not out-of phase like the W8JK.

Low radiation resistance is a consequence of tight coupling between the
closely-spaced elements. This makes the coupling to the array likely
lossy in making impedance transformations necessary to match the array
to the transmission line. Kraus has some suggestions on how to make
these arrays more compatible with their transmission lines.

I f this were a hospital you couldnt distinguish the doctors from the
patients.. LMAO

If you are implying that Richard is incorrect in his statements and that
Art has even a tiny clue about reality, you are sadly mistaken.

You should study a bit about the subject before you criticize the
"Doctors".

Not what I am implying at all, that wouldnt be funny. I only wish I knew as
much about antennas as Richard.

I only recently obtained copies of books by Krauss and Terman and have begin
to intensify my studies of the subject.

While on the subject, I obtained my first class FCC license in 73 and the
material in Terman seems to fit very closly with the study material I had.
Is there a connection between the test and Terman's book?

Well, then I won't comment anymore. Did you buy the license?

No I wish I had had the book then, I took a course(before Bash) at the time
that also seemed to follow Terman. When I went up to Atlanta to take thes
test I only thought I was giong to take the parts for the second class
license and passed the test for first class also. I felt like I didnt know
my own name when I was finished and had no clue whether or not I had passed
even the second class portion. I really didnt believe I had. Funny thing is
I have never used the license. Stiil just skiming the books but Terman seems
a little elementary now and Kraus is going to require me to bone up on my
calculus, something else I havent used since 1979. Hell I dont even know why
I am bothering, fine cooking and ballroom dancing are much more important to
me now.
