It was not so long ago you were whinging because art had not
told you how to build his antenna, I suggest you build one and find
out if it works before you
rubbish all, stop acting like the asshole you are, either you are
interested or you are not, make up your mind. Your knee jerk posts are
getting booring.

Not really.

For examples, over a given r-f bandwidth:

- Radiation pattern throughout the free-space radiation sphere?
- Free-space gain with respect to an isotropic radiator (dBi) or a
matched, 1/2-wave dipole (dBd)?

Note that any particular r-f termination may have low feedpoint VSWR
over a considerable bandwidth, for some reference impedance value --
but that does not necessarily make it a useful antenna (think: dummy
load).

In my previous post in this thread I asked about the gain and pattern
of this mesh antenna. Hopefully the inventor will respond when he is
able.

But being curious and not wanting to wait, I went back to his previous
thread about small antennas, and modeled what he posted there -- just
to learn what NEC would show for those parameters.

The results are given in the link below.

The h-plane azimuth gain of this mesh antenna is far from uniform, and
its 0.0134 + j85.45 ohm feedpoint impedance is very unfriendly --
though the frequency is centered in Art's stated VSWR bandwidth.

Even if this feedpoint Z was perfectly matched there to a 72 ohm
balanced transmission line, this mesh antenna would still be a poor
radiator compared to a 1/2-wave dipole.

So then, based on all you've learned from Art, why don't you give a
brief description of an antenna based on Art's principles. Please give
some dimensions.

Please, Tom, this is like rejecting the discovery of stumbling across
a piano bench frozen into a glacier. Art would expect us to next find
the piano, look at the music stand and discover the concert that had
been composed.

Hummm.. Maybe so. I was starting to think he had a new trunk monkey
to do the dirty work dealing with the vast legion of non believers..
IE: non believer asks for more details.. Trunk monkey throws bananas
at him, and then runs up and starts humping his leg.. :(

Hence, Art is an evolutionist? ;-)

Evolved? Never.
Revolved (Corriolis)? Perhaps.
Devolved? Almost certainly.
According to Art, himself, he would a levitationist.

What would account for his astonishing description?
"Thus we have three types of Leptons
each able to produce one of the primary colours,
red, green or yellow."

I wonder what happened to Blue (or ultra blue for that matter, or even
X-ray). It might astonish Art (belay my last, that isn't going to
happen) that red and green combined ARE yellow (how does that not
happen in Art's side of reality?). Even Newton understood this. Of
course, this may be Art's spit-on-Newton week.

Biggest difference being that Chip at least had some connection with
reality. And Jaro is an idiot or a close approximation of one.

Agreed.

"Art Unwin" is playing some of you guys like a cheap fiddle. For all
we know, Art is a pimply-faced 14-year old, armed only with a
thesaurus and delusions of adequacy. He might qualify as Exhibit A in
a college course in Abnormal Psychology.

I stopped taking any of his posts seriously several months ago.
Coming soon, the next step: ignoring any threads in which his name
appears.
