For himself.

Artifice: I have a novel and mysterious design emploiting Rutherford
partical evasion without baluns and using a gauss reflectionater.

Ham: What is its front to back rejection?

Artifice: I gets signals in all directions! Not just front or back.

Ham: Then why do you say it -um- evades something or other (sigh)?

Artifice: Well, this is not part of the design of not getting the
forward proceeding back signals.

Ham: So, it doesn't work.

Artifice: It works perfectly, just not as well as gaussian
reflectionating mechanics would expect unless these particals are
accelerated to high speeds by the weekend force.

Ham: So, why doesn't my antenna get this kind of signal?

Artifice: Because you read books from the libraries of the hooded
priests who refuse to backnowledge my inventions!

Ham: Why would I want to listen to these signals if I read your
books?

Artifice: Then you could enjoy the Fill-harmonic richness of my
single channel stereoid transmissions.

Sorry Richard, but that's definitely Memorex. Nice try though.

Scanning past antenna papers point to the use of a cone shape similar
to a horn of 2 metres diameter
produces better results. The antenna needs a longer mast so at the
moment I can't compare
F/R. Either way, with the radiator within the reflector envelope it is
difficult to understand what creates
a rearward lobe regardles of scale or frequency of use with respect to
receive. At the moment I see nothing that points away from the
Rutherford particle experiments with foil .ie penetration when at
right angles , deflection at other angles.

As usual Art you are avoiding answering the questions and choose to confuse
the issues
with you own preconceived ideas and terminology. The fact that the feed is
totally within the "reflector envelope" tells you or us nothing about
sidelobes and edge taper.
I really don't think you want answers, but I'll try once mo
1. What frequency
2. What is the dish diameter
3. What is the dish focal length to diameter ratio (F/D)

Dale W4OP

I am not avoiding questions, just those that appear irrelevant, but
here goes Anything to make you happy, this should be interesting how
you use these answers with respect to the posted question

1 160 metres upto 2 metres, tunable

2 2 metres

3 Doesn't have a focal length, it is an end fed ( series connection)
helix antenna.

At least to the best of my knowledge which is why I posed the question
Hopefully we will all stay on subject and not get side tracked. I will
leave it to others to respond to Richard when they determine what he
is talking about.

20 postings to get to the point (not unanticipated, however) which Art
calls "irrelevant."

As for those answers?

Hence the wholesale disregard for first principles in size vs.
wavelength. Elementary analysis need not go any further when failure
is so obviously designed in.

3 Doesn't have a focal length, it is an end fed ( series connection)

-Well, maybe not obvious to everyone.-

But why don't we chalk this design up to S U C C E S S and call it a
thread? If this bier gets anymore wreaths tossed onto it, it will
kill the pallbearers.

The posting is about dishes not antennas. I have not read about a dish
that does not emit signals to the rear. Now I have built one and find
to my surprize that it does accept signals from the rear ! All very
simple, the radiator is resting at the bottom of a cone and the top of
the radiator does not stick out beyond the reflector. Since you do not
know what you are talking about and intent is to disrupt this thread
why on earth are you muttering about nothing at length? Simple
question has been posed and obviously you do not know the answers that
antenna engineering knowledge would provide as you are not an engineer
but a actor or actress by day and by night. My question remains
unanswered after all these posts.How do signals arrive or depart from
the rear of a dish or horn? We all know that you don't know the answer
but there are qualified engineers in this group who possibly doand
willing to share.

Your antenna has nothing to do with dish antennas, bu rather plane
reflectors (of which yours is way too small as Richard pointed out).
I know we cannot change your opinion or teach you anything- so I am out of
here.

Well, to start with Art, a cone reflector doesn't meet the definition of
a dish antenna.

I'm sorry, but they just aren't the same thing.

I surprizzzed you missed the difference.

Oh, I have just popped in and saw Richard up to to his old tricks with
Cecil. I don't really expect a satisfactory answer. All on this group
denied it was possible to expand Gaussian law of statics to the laws
of Maxwell so there is nobody with a real feel with respect to
radiation, and of course it shows! Same goes for the nature of Richard
no matter how he tries to hide things. The KB9 station and his foul
mouth friends are what I was referring to and is why they are pleading
for a moderator for this newsgroup. Not really the type I wish to
associate with. When the group deviate from the question at hand is
when I leave as they all eventually do.
Within the next few hours they will want to ask questions about you
know what to cover their ignorance and Richard will come prancing in
again with his long leg mesh underware acting out a shakespere scene .
A few years on a ship tends to change
how you look at life so that he walks in the snow with his foot prints
in a straight line
so that the torso wobbles and then there is the way that he acts and
speak.
My question is still there and regardles of the number of postings
made I doubt that it will be answered. This newsgroup becomes dull
when radio goes out the window and personal attacks begin so one
really gets what he wishes for when they hang around.

Dale, my response above was with respect to Richard not you, but I did
know you would run eventually. Study the math of Maxwell and Gauss
before you decide to take up teaching.
