Put the request into your Maxwellian based radiation computor program
if you are
not to lazy, where you will learn details of the GUT that Maxwell
failed to provide.
The holy grail is no more!

Does this effect my HF arrays?

In the real world we try to get maximum results with minimum investmennt
in effort and materials. An unbalanced 1/4-wave or a balanced 1/2-wave
seems appropriate.

As far as angles go, polarization is the direction of the electric
field, usually horizontal or vertical for mechanical as well as
electrical purposes.

You can take Kraus to the bank. Check his index for "Mutual Impedance"
of paralleled dipoles or echelon antennas. Better yet, you likely have
experience with trials of cross-polarization of VHF or UHF antennas. You
have seen the havoc cross-polarization causes. Now, is there any angle
between fully aligned and completely misaligned where we discover a
magic peak? Of course not.

O.K. you WIN Richard. You run so many different routes that
I can't keep up with you. You deny the validity of computor programs
and Roy sulks because none of his programs have the optimiser feature
which is the easiest way of solving the question.
You can place the radiator where ever you want to get the results
that you would like to see.So you don't trust computor programs,
programmers or you just never tried to use them?
You can now get back to argueing with Cecil on coil currents
which will allow some more disconnecting reading from Terman
of yesteryear. There is nothing more to be said regarding
the resultant vector of a radiator's active vectors which is
the basic issue that I was discussing in the first place.
Hopefully you will recover by morning and look on life
in a different manner.

It isn`t a competition. It`s a discussion. Art is aware that the
electric field vector is at right angles to the magnetic field vector
and that both are at right angles with the direction of propagation.

When the receiver`s electric vector is aligned with the transmitter`s,
their magnetic vectors are in alignment too. Communications couldn`t be
better to the best of my knowledge. With circular or elliptical
polarization, we worry about right hand or left hand polarizations, but
I`m assuming linear polarizations. There is a wave tilt associated with
propagation along a lossy surface, but I`ll be darned if I can grasp
Art`s tilt factor.

That is because you quote outdated technology and have lost the means
of deduction for yourself. You are not alone. Apparently the group
itself are in the same boat. Somehow it seems a bit rediculous that
we have a group for discussing antennas where NONE can deduce the
most efficient angle of a radiator with respect to ground when
desiring maximum horizontal polarisation gain with the majority
having possesion of an "american" degree!
It seems rediculous that a argument on just a coil can go on for years
with nothing to show for it other than talking about it forever
and displaying their ever growing testerone level in a fashion that
pushes aside all other discussion. If you were willing to accept
computor
aids in your life and learn how to use them you could leapfrog
into the present age. But you are to lazy and to old and unwilling to
change
thus relying on a education that is over fifty years old.
You just cannot have reasonable communication on antennas or
anything else by disregarding present science and substitute insults
in the place of knoweledge ,or for that matter, quoting a books
writings
not pertinant to the subject at hand.It makes no sense for anybody
that
is interested in antennas is not interested or care about any radiator
other than those that are planar . That also goes for the naval
academy in
Washington and NASA and other institutions.

My mother 78+ has trouble with her cell phone ... I shudder at teaching
her the ins-and-outs of a programmable calculator ... long hand
calculations take time.

Some are stuck with antenna modeling programs ... indeed, a tribute to
them for mastering those. The world will not change at a snap of your
fingers.

I have a smith chart program, that is enough for me--Cecil does it by hand!

O.K, Not much technical content in that posting, nor hint of what Art
hopes to do with an 80 degree tilt. Maximizing horizontal polarisation
is another mystery. Vertical polarization is the way to launch
groundwaves and it will be so 100 years from today. Modern technology is
unlikely to improve the FCC approved antenna and grounding systems used
in AM broadcasting, thanks to RCA`s B., L., & E. (1927).

The coil argument has persisted a long time but it has provoked some
searching into the behavior of inductance. W8JI may be on to something
but he may not have it exactly right. Terman and Lenkurt have the TWT
down, as invented in England (1943) but its coil is stretched out so
that a foot long coil only has a dozen turns and lacks tight coupling
which might work as W8JI describes.
