Oh come on Wes look at your last posting where you poked fun at the idea of
a polygon phasor array. And look at the other postings where it was obvious
that many were not familiar with the same and needed more direction. Look at
Roy,
he admitted he knows nothing about the subject
He did no such thing. Not only are you having difficulty expressing
yourself, you have similar difficulty understanding what others are
trying to tell you. I'm not trying to be cruel or harsh, but that's
just the way it is.
which when he next argues with the like of Cecil and others I will now have
to think twice instead of accepting his typical
riposte that he supplies. But I give Roy credit for being honest in the face
of personal embarassment regarding his lack of knoweledge
You say it was not necesary to provide a long convoluted pseudo treatise on
vectors but many asked for it and you made a joke of the idea,
Regarding front to rear occuring at the same frequency. An operator wants as
much gain as possible when communicating
so he does not need to resort to more power than needed. For best
communication it is nice to block of interference to the rear and thus he
needs best front to rear at the frequency of communication even tho it is of
interest that he had better rejection at a lower frequency. The fact of the
matter is that it is not the frequency being used, he has to live with a
lesser value of rejection, your opinion may well be different.
So if I understand you correctly ( a *really* dubious proposition) I
would have much better success with my 20 meter antenna if I embraced
your philosophy. My current antenna is of my design, a three-element
monoband Yagi-Uda parasitic array. You can see it in the picture on
qrz.com. It is an honest to goodness actual antenna. I have 310
countries confirmed on 20 meters most of them (The hard ones) worked
with this antenna. All at the "too-low" height (according to you) of
45' above ground. I would be delighted to send you an EZNEC,
Multinec, or NEC file that describes the antenna. The model accounts
for boom to mast connection, element taper, etc. (per Leeson,
"Physical Design of Yagi Antennas."), includes the stub matching feed
system and appears to accurately describe the antenna to the best of
my limited capability to measure it.
Over the band of interest, 14.0 to 14.25 MHz., the modeled free-space
FB exceeds 20 dB and the gain varies from ~ 7.9 to 8.15 dBi. The FB
peaks at ~ 14.12 MHz and the gain is maximum at 8.15 dBi at 14.25 MHz.
Pray tell, what operational advantage am I giving up because the gain
at 14.12 MHz (the FB peak) is *only* about 8.0 dBi instead of 8.15
dBi?
Now you also remarked that you do not want explanations, just the meat. I
gave what you call a "treatise" that explained the theoretical
underpinnings of what I have stated. It would be unwise at this point to
declare success without not only having a NEC model to confirm it but also a
20 meter antenna and not say a 144 meg equivalent. Today we had snow, wind
and rain so I could not complete the job.If by chance the antenna gives a
third aproval i.e.Nec model then polygon discussion plus the antenna then I
will forward it to RADCOM for peer review. It is at that time you can vent
your displeasure that you rejected my offer to share the actual mathematical
and physical findings. If you were looking for a way to undermine what I had
stated then my " treatise" now arms you with the knoweledge to disprove what
I have stated as it is one factor that convinces me of my origonal findings.
If you need more information regarding vectors I will be happy to aid you in
your quest
No, I don't needed any more of your help with vectors. I wish you
every success with your RADCOM paper.
