maybe you should hook one up to your magical neutrino antenna and see if you
can measure the weak force tilt frequency in your drunken vertical.


David
You have stated that you have the smaller AO program (limited in
pulses) but as
yet you have not proved to anybody that you know how to use it !.
If you insert dimensions for a vertical radiator where none of the
dimensions for XY and Z
are repeatable then the program gives you picture of the weak force
and it's angular direction
..Not only that my friend, it also shows that with the use of this
vector ( the weak force remember)
it shows what the position the radiator must take up for maximum
gain !. Drunken vertical indeed!
On the other hand you can continue the mistaken idea that
intercoupling of radiators provides the same
gains as Maxwell who includes the weak force in his calculations for
absolute accuracy.
Remember what I have told you " A radiator can be any size, shape or
elevation as long as it is in equilibrium"
This is contrary to what the experts say that a radiator MUST be
straight, which is absurd.
But then you rely on absurdities.
Your friend

until you point out the term in his equations that specifies the weak force
you are just handwaving.

David, you just have to be a leader in this. Total reliance on books
or even on wilkapedia
is for the birdes. It is upto you what rock you build your reputation
on.
Going to school only brings you up to date with other peoples
thinking so that
when you leave you don't have to reinvent the wheel. For the
increasing number
of head woblers that are join ing the hobby that is understandable but
for those who sought
education as a means of just making money is really stealing from the
next generation.
Education is meant for the advancement of the human race where
continued scientific
approaches after school was meant to correct the errors of the past
to strengthen the rock
for the next generation to build upon. Denial of progress or the
effort to prevent change is just theft
so that the children have to follow the selfish efforts of their
elders. Change will come with respect to antennas
tho probably after you have gone. You may posses the direction at the
present time of a generation but soon you will be gone
and the human spirit formerly chained by their elders will re emerge
in disbelief of their elders folly who while dwelling in a garbage
can felt safe from intruders, learned to ignore the smell that became
associated with them feeling that they had won the conquest of change
prevention
Your final place of rest will be in a hill amoung friends but without
a voice.

While visiting a cemetery in Smog Angeles, I saw several monuments
that included a recording of the deceased saying a few last words.
Push the button and it plays the recording. That was many years ago,
and I suspect they've gotten better with video clips and LCD displays.
Maybe the next step will be a 3d hologram. You may be dead, but you
can still annoy the relatives.

computors and there are 2.4 Ghz
spectrum analysers out there as well as audio set ups for computors.
So what is available today for hams
in the HF BANDS? There are a lot of older type audio S A s on E bay
but I haven't heard of anybody modifying thoseand with most having
computors it would seem reasonable to think that there were components
available that could performn between audi and 2.4 Ghz. So has anybody
seen any modern type DIY spectrum analysers
around for sale or kits? I have 141t and other types of SA which now
are considered bulky and I would really like something smaller or say
modify something like a audio setup as a project.

To work with an SA on antennas you will need either a
"noise generator" (modern method) or a tracking generator
(old method) which can control the SA.

better go for a scalar analyzer or if you can afford it,
get a vector analyzer

Like the TAPR TenTec VNA.. very nice piece of gear, but does have a
broadband detector, so it won't work as a spectrum analyzer, nor is it
going to work well in a RF dense environment.
