Would anyone have a copy of an article from either 73 or CQ magazine
somewhere around the 90's which contained an article on how to
construct a Fractal Quad antenna for 10 metres. The design was based on
work done by Nathan Coen N1IR.

No he isn't a buffoon, he had a Doctorate! Yes this group did go after
him with insults e.t.c. until he finally left and went into business
leaving the group devoid of experts again. He has several law suits
filed against the biggest phone makers in the world where they were
using his ideas with out his knowlege and not *paying for them.If it
is found that he is correct that other phone makers felt they had to
use his ideas to stay in business then it would appear the ideas had
merit.
He wasn't the last antenna expert to leave the insults from this
group,
Tom W8ti was one , Litchfield is another who left, Llewellen rarely
appears now and there were a lot more that left. The pseudo experts
are still here and easily recognisable and there are many a day that
the newbies will not come near this newsgroup to ask a question. No,
Chip was not a buffoon and is laughing all the way to the bank despite
criticism from those from those who decided there was no need to go
to *college or even high school because they could holler louder than
anybody else and win.
Apparently it is" Fractus" *that is the company sueing several
companies and not "Fractal"antennas. I thought they were one and the
same companies,So I am in error. Thus I apologize for this error. *So
let it be clear, that it is not Chip and his company that is pursuing
the other phone manufactures but another company of like
name
With respect to Chip's designs. What I consider important is that his
radiators do NOT contain, or produce, any lumped loads in their
manufacture that are not canceled leaving just distributed loads. Thus
for the given actual length of the radiator ( the equivalent stretched
radiator length) the impedance is strictly resistive, neglecting
proximetry effects. *This meets the intent of Maxwells equations where
lumped loads DO NOT EXIST when accounting for all forces involved in
radiation. The only deviation from Maxwell that I can see is that it
does introduce sharp bends which also introduces phenomina with
respect to current lamina flow, where excess eddy current flow is
introduced, which is additive and not subject to cancellation.

Art, how does a current through a lumped inductance behave contrary to
Maxells equations?
Jimmie
That is pretty obvious! If you review Maxwell equations you will see
reference to root L.C, where L and C refers to distributed loads only
and is not inclusive of lumped loads. Adding a lumped load introduces
unbalance or a deviation from equilibrium, which is a fundamental when
reviewing the laws of the Masters.
Mathematics demands of every equation that the metrics MUST
cancel to zero. Thus *all metrics involved must consist of pairs.
If one introduces a lumped load via building considerations then
another one has to be introduced so that the metrics are able to
cancel
out to zero.
*In the case of the slinky antenna it thus demands that the windings
must be equal and opposite.

always good for a laugh isn't he jimmie?
