[HCRA] Antenna Design

[Mike DeChristopher]

I have seen this already on several groups, and on the TowerTalk group they
ripped into it.  Someone brought up his claim to 80-100% efficiency,
although if he melted one with 100W - and on 15 meters - who knows.

It seems that this "distributed load monopole" is actually more of a whip
than a true monopole, and although it magnifies a need for coils, does the
performance actually increase?  Another user commented that this type of
load was used in whips in the 70's-80's without much increase, if not a
decrease - not to mention the size and wind resistance.

In an article found at
http://www.eet.com/at/news/showArticle.jhtml?articleId=21401977 he mentions
something about a two-dimensional helix, something that will revolutionize
HF resonance...looks like a folded dipole, tipped vertically, with a loading
coil AND balun in the middle.  He says that he has made contacts on 160 and
80 meters.

"With my technique, I reduce the inductive loading that is normally required
to resonate the antenna by as much as 75 percent . . . by utilizing the
distributed capacitance around the antenna,"  I agree that it does sound
promising, but strange at the same time.

So, now we're down to quarter-wave?  I would like to build or test one of
these new DLM's and compare it to a full-wave antenna - assuming, of course,
that the molten metal wouldn't burn the grass...
