If it causes you too much pain to tell us why it's an antenna worthy

LOL, I can see in his answering post, that he did indeed ignore
your valid question, and spewed forth the usual whiny drivel...
Woe is me, sayeth Art...
Note this comment...
""You could change the subject to the patent on Constant Impedance
Matching System since that also was rejected by the amateur
masses on this newsgroup to add fresh fire to the conversations. ""
Heck, I modeled his small loop/cap thing and proved it did work.
Just fine as far as matching is concerned. But I didn't agree with
his other claims. IE: that there is substantial radiation from the
loop,
etc. He claimed you could steer the pattern, by changing the value
of the cap if I remember right.
I modeled said device, "I called it a loopole", and showed that this
wasn't true.
But I never said it didn't "work" as far as a matching device.
I just said it didn't work like he thinks it does.
This was basically ignored.. He has a fine system of ignoring
any information that does not suit his agenda.
The only problem is I have a fairly decent system of detecting
BS... I really don't even have to know much about whatever it is
being discussed..
If it's BS, I can usually smell it a mile away.. I may not know why
I smell the pecular aroma I do, but I will smell it none the less.

I never modeled it but it seemed that for all practical purposes the cap
was shorted by the low inductance of the coil/loop and should have from no
to negligable effect on tunning.

Jim, You never modelled it? The capacitor changes the frequency of the
loop.
Thus you have 2 current curves with the loop in the center.
Ofcource the current at the ends of the element is always zero
when the loop is resonant. When the frequency gets to 28 Mhz it is
basically two dipoles side by side with the loop at the center.
If I remember rightly for the loop you need a 5 thru 50 pF variable.
Frequency responce is 14 thru 28 Mhz. But that antenna is from the
past
ie constant impedance antenna.
The newly provided antenna is just a three element on a boom which I
have compared with a ARRL optimised antenna that they have in their
antenna handbook.People like comparisons so I supplied comparisons,
mine compared with the ARRL antenna. Ofcourse mine is half the boom
length of the ARRL form and with more gain. This should give even
novices something to look at tho Extras will still complain.
Element lengths are similar in both models so you could call both
of them Yagi's or anything else that you want to call them.
The new antenna does not follow the general boom length/
gain antenna curve that is printed in most antenna books
for a Yagi tho I suppose that doesn't matter much to some.
Somebody however will find something to complain about so
it should be interesting to see what they can come up with.
Both by the way have a single feed point if that matters.
