Not necessary Dave. Richard is very familiar with the

I want to hear it straight from the source. I have

for
you to define the terms and you can't put it into words
this
poor

can understand, so i thought we would try to build an

the
whole
thing
is
just out of my reach and i should go back to good old

Make a dipole of random shapes and heights that is resonant
at your design frequency. Note the radiator can be any length
as long as it is resonant. For the sake of this discussion
or interrogation let us use a plain half wave dipole.
The feed coax feeds the dipole at it's center in the normal way.

ok, so its a plain half wave dipole, fed with normal coax in the

Because it's resonant at the desired frequency. This is the
basic form of a Gaussian antenna which is also the starting
point of a Yagi antenna if viewed as a single radiator

so 'gaussian' == 'resonant'
why didn't you say so in the first place?

First David before I go on others may jump in
and take the thread away from you. If that occurres
we can talk via E mail so that you are not penalised
They can use another thread in parallel which
I will respond to. This thread will remain a
civil and academic interrogation as you have requested.
.........
No, I would not stretch things that far based on
just one element or one piece of a jigsaw puzzle
A Yagi array is based on an array of elements
not just one. You wanted to procede in small steps
as provided by you, specific and to the point.
For starters a Yagi array is planar and a Gaussian
array antenna can be and usually , from my
research, is otherwise. Note the Gaussian element
is of random shape and height but always resonant
and not necessarily tied to a 1/2 wl.
Art


no, the interrogation isn't over... it was just my bedtime.

ok, so ignore the yagi for now. you classify a resonant random length wire
as a gaussian element. is there any other essential characteristic besides
resonance? How does 'equilibrium' fit into the description?

First of all we are talking about arrays and not just a
single element . Now one must consider where to put the
next element. If we are space concious it would seem that
putting both elements close to each other but not as close
as the wire dia compared to the spacing. This element has the
same confines as the first element so one must attain
resonance of both elements at the same time while in
the proximetry of each other which allows for a descision
loater as to which element/s is going to be driven.
Ofcourse you will notice that major differences occurs
to the norm because of the close proximetry of the elements.
Since I suggested that we use 1/2 wave elements it would
also be advisable at this time all elements straight
but at different heights and angles to each other
so that multishaped elements,which can be used, do not
complicate the theme of what I am describing.

( The following side note goes beyond what the question
is but I am sure it will help the further you travel down the road.)

What we are now simulating is a Gaussian field with
its normal pill box. Normally one only sees static
particles in equilibrium but I have taken the liberty
of adding the array elements upon which the static
particles are resting upon and inside the arbitary border.

specific shape, as long as it is resonant. But is resonance alone enough to

Yes, if it is in place where it is determined to be
resonant because that takes consideration of it's surroundings.
If one takes the surroundings into account one is taking
into account equilibrium
I say this because this interrogation could then
decide to move it and still call it a Gaussian antenna
and say they have a gottcha!
Please excuse me if I am a bit wary of how the questions
are placed and for what reasons. But I don't want
to be part of a word game where things can be misconstrued.
Civility must be kept without being underhand if your
intent is to be pure.

you to define the terms and you can't put it into

maybe
the

Sounds reasonable


if it sounds so reasonable, how many wires does it
take?-

no, this is my subject so i'll say when it's dead... i

ok, thats a start.


assuming i want to operate on 14195khz, how long should
the
wire
be?-

Whatever wire you have throw it away and get a longer one


ok, random length... can do. now how do i connect it to a
piece
of
coax?- Hide quoted text -

O.K. For the last time I will go along until such time
it is obvious you have other intentions.So I start again.


Make a dipole of random shapes and heights that is resonant
at your design frequency. Note the radiator can be any length
as long as it is resonant. For the sake of this discussion
or interrogation let us use a plain half wave dipole.
The feed coax feeds the dipole at it's center in the normal
way.

ok, so its a plain half wave dipole, fed with normal coax in the
normal
way.
so what makes it 'gaussian'?- Hide quoted text -

Because it's resonant at the desired frequency. This is the
basic form of a Gaussian antenna which is also the starting
point of a Yagi antenna if viewed as a single radiator
Art


so 'gaussian' == 'resonant'
why didn't you say so in the first place?
so a properly tuned yagi-uda array is a 'gaussian' antenna?- Hide

First David before I go on others may jump in
and take the thread away from you. If that occurres
we can talk via E mail so that you are not penalised
They can use another thread in parallel which
I will respond to. This thread will remain a
civil and academic interrogation as you have requested.
.........
No, I would not stretch things that far based on
just one element or one piece of a jigsaw puzzle
A Yagi array is based on an array of elements
not just one. You wanted to procede in small steps
as provided by you, specific and to the point.
For starters a Yagi array is planar and a Gaussian
array antenna can be and usually , from my
research, is otherwise. Note the Gaussian element
is of random shape and height but always resonant
and not necessarily tied to a 1/2 wl.
Art


no, the interrogation isn't over... it was just my bedtime.


ok, so ignore the yagi for now. you classify a resonant random length
wire
as a gaussian element. is there any other essential characteristic
besides
resonance? How does 'equilibrium' fit into the description?- Hide

First of all we are talking about arrays and not just a
single element . Now one must consider where to put the
next element. If we are space concious it would seem that
putting both elements close to each other but not as close
as the wire dia compared to the spacing. This element has the
same confines as the first element so one must attain
resonance of both elements at the same time while in
the proximetry of each other which allows for a descision
loater as to which element/s is going to be driven.
Ofcourse you will notice that major differences occurs
to the norm because of the close proximetry of the elements.
Since I suggested that we use 1/2 wave elements it would
also be advisable at this time all elements straight
but at different heights and angles to each other
so that multishaped elements,which can be used, do not
complicate the theme of what I am describing.


( The following side note goes beyond what the question
is but I am sure it will help the further you travel down the road.)


What we are now simulating is a Gaussian field with
its normal pill box. Normally one only sees static
particles in equilibrium but I have taken the liberty
of adding the array elements upon which the static
particles are resting upon and inside the arbitary border.


whoa! too fast! lets talk about the minimum antenna, the 1/2 wave (or
there abouts) resonant element. You said that was all i needed to make a
gaussian antenna. So it doesn't have to be a classic dipole or any other
specific shape, as long as it is resonant. But is resonance alone enough
to
classify it as a gaussian antenna?


Yes, if it is in place where it is determined to be
resonant because that takes consideration of it's surroundings.
If one takes the surroundings into account one is taking
into account equilibrium
I say this because this interrogation could then
decide to move it and still call it a Gaussian antenna
and say they have a gottcha!
Please excuse me if I am a bit wary of how the questions
are placed and for what reasons. But I don't want
to be part of a word game where things can be misconstrued.
Civility must be kept without being underhand if your
intent is to be pure.

Equilibrium between an antenna element, of course.
