Ok, lets try it this way... step by step, inch by
inch,
we
may
yet
figure
out what this antenna is.

First question:
What is the least number of wires needed to build a
gaussian
antenna?

Not necessary Dave. Richard is very familiar with the
subject
at
hand
as well as its underpinnings that can be understood
by
EEs
and is providing a reference that will make all
things
clear.
You asked for it and your wish is going to be granted
in
a
clear
and precise manner that you and the group have
requested.
You should now be able to build it yourself with out
mumbo
jumbo
from me to confuse you.
No need for me anymore, you now have an expert at
your
call.
Don't forget Poyntings input.

whats a 'Richard'??

I want to hear it straight from the source. I have
asked
over
and
over
for
you to define the terms and you can't put it into words
this
poor
engineer
can understand, so i thought we would try to build an
example
from
the
bottom up. but if you can't help with that then maybe
the
whole
thing
is
just out of my reach and i should go back to good old
yagis
and
phased
arrays.- Hide quoted text -

Sounds reasonable

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

As many as you want and have fun.

no, this is my subject so i'll say when it's dead... i don't
want
to
know
how many i can use, i want to know the minimum number

One

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.
Art KB9MZ......XG

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

- Show 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 quoted

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?
