A lot of words. As far as mathematics is concerned I started with the
Mathematics of Gauss and Maxwell and found they were mathematically
connected. Nobody on this group agreed with that posture of mine.

On the contrary, it was pointed out many times that Gauss's Law is one of
the basic Maxwell Equations, so they are definately bound to each other.

So as far as mathematics goes with this group is straight out of the
window!

So as far as your understanding of the Maxwell Equations, you are straight
out the window.

Cecil tried that aproach and failed also. Now you are
proposing that mathematics is the trail that reveals all.

unfortunately art has strayed so far off the trail that he'll need a
spiritual guide to help him back to the light of day.

Well David
I have now finished all my work on the antenna except for a couple of
bells and whistle that can wait for the balmy days of summer. Swr
along the frequency span
is similar to that of a log periodic with a slight waveiness but that
can be altered remotely quite easily as well as a couple of other
things.
Jim, I will be finished on the other today and will be in UPS on
Monday.
I will not test before hand but leave that up to you. Will E mail you
later with details
By the way David, the antenna will stay at ground level and I will
take the one off the tower as height is not now a consideration
I suppose I will now have to think about taking the tower down as it
is not needed anymore which will make the wife happy.
This week end is now for the wife and her birthday. After that I will
exercise the new antenna with a special look out for you.
Regards, your adversary
Art

well, what is the beamwidth and frequency range??

I'll make it easy, 10 degree beamwidth and 30MHz bandwidth.

At how many GHz?

The problems of poor reporting are creeping into the lack of specific
questions.

An example:
Inventor
I have this patent that proves my technology.
Questioner
It shows the reflector is smaller than the driven element;
it shows the director is larger than the driven element;
Does this prove the Yagi no longer works?
Inventor
[silence/mumbling/outrage] I didn't come here for ad hominem!

A reflector can be shorter or longer than the driven element in planar
designs especially Yagis with two reflectors. Shakesphere should have
told you that !
David, the antenna covers the distance covered by a mfj 259 b which is
1.7 to around
175 mega hz. Obviously it therefore has no limits above .Below I
cannot measure unless I modify my radio outside the amateur bands, ie
reflect swr outside the ham bands. Beam widths I can't determine as I
do not have enough segments available on my optimizer program . But I
believe that can be accomplished.
Check out the SK list regularly as I may leave the answer in my will
if it mentions you.

At 160m. You can't possibly have missed that, Richard. Art has stated
it dozens of times. Maybe hundreds.

He's nuts, and very thorough about it.
