Yuri, K3BU has declared victory in the "current drop" argument. It`s in
a new thread: "Current in loading coil, EZNEC-helix", after measuring
current in and out of a loading coil again.

I am reassured when math and models agree with measurements.

There is no such thing as a "current drop." As for Yuri declaring
victory, that's easy enough to do since the person he's declaring
victory over, Tom Rauch, isn't bothering to refute him on this
newsgroup.

That is not science, it's closed-minded

I'l second that!

Hi Yuri,

Thanks for the flowers... it now appears
EZNEC may not be all that it is capable of...

The extreme example comes from continuous loading. The entire antenna is
a solenoid or coil of wire. The impedance at the tip is very high. At
its feedpoint, the impedance is low. The current in the coil tapers from
one end to the other. Adding conductors to either or both ends of the
coil changes the current but does not usually eliminate current taper in
the coil.

Best regards, Richard Harrison, KB5WZI


=====================================

It is important to make clear it is NOT a linear taper.

The current and voltage are distributed along the helix in Sine or
Cosine-form as with a 1/4-wave resonant wire antenna.

Adding conductors to its ends merely truncates the same kind of
distribution.

This applies to both short-and-fat and long-and-thin helices.

Instead of confusing the issue by stretching the imagination and messing
about with reflections and standing waves, analysis of behaviour is more
simply and accurately done by basic transmission line formulae.

Which automatically takes the coil's all-important capacitance to the rest
of the world into account.

Zo = Sqrt(L/C).
Velocity = 1/Sqrt(L*C).
Phase shift = Omega*Sqrt(L*C).

It's as simple as that!

PS. Replace "does not usually eliminate" with "never eliminates"

Hi Wes,

While what you say may be true, it
proves nothing, in that performance is
observable and comparable, and does
not require blind faith to observe it.

Let me show you how this works.

I _personally_ guarantee you that my design for a 3-element 20-meter
Yagi will out perform any Raibeam of the same boomlength and at the
same height above ground. (I'll leave out the "electrical
boomlength", whatever that means)

Now it is up to *you* to prove this claim false.


Since you are making the claim, and
there exist untold numbers of Raibeam
antennas that have consistently beat
antennas of your design (a yagi is a yagi)
in pileups, etc., the onus would be on
you to prove your claim is valid.

Conversely, if there were thousands of
your 3-element 20-meter Yagis that have
beat out the Raibeam antennas in pileups,
and the Raibeam guy makes such a claim,
then it would be up to the Raibeam guy to
prove his claim was valid.

It is all a matter of what has been
established by many instances over
time.


And like any good huckster, as "proof" of the superiority of my
design, I offer these testimonials:

With the antenna at a modest height of 50' above ground and fed with
250' of coax, in the recent ARRL Field Day contest Single-op N7WS was
able to hold a frequency while running 100 W (SSB) on emergency
power. In only 17 hours of operation 1357 20-meter Q's were logged.

Great... but a single case establishes
nothing.

twice on SSB (this ****ed them off, but I'm tired of not being in the
log when I know that I worked them), on the first call, and also

http://dx.qsl.net/cgi-bin/logsearch.cgi?L=yv0d&C=n7ws

Etc., etc....


It is a well know fact that Pat Murdoch,
ZL1AXB and I, both running 4 element
Raibeams @ 40 ft, held a daily sked
for close to four years, throughout the
bottom of the previous cycle on 10 meter
SSB, with power levels never exceeding
500 watts PEP. In only about 5% of the
total contacts were the sigs too weak to
hold the sked.

.... the only signals on the band...

With that antenna, Pat won first place,
single op CW, in the ARRL 10 meter
contest both in 1996 and again in 1997 -
the only years he participated.

http://www.raibeam.com/page11.html

In the years he participated in the WPX
and CQWW contests, you will find Pat
listed in the top 10m positions as well.

Now, addressing your first assertion:
Pat can hardly be a deluded Raibeam
*cult* follower, since many of his
experiences are a matter of record.

And that does establish something.

Hi Wes,

Unsubstantiated in your mind perhaps...
but there are many with first hand
experience ITR who would strongly
disagree with that baseless opinion.
Baseless, in that it lacks first-hand
experience to give it substance.

BTW, That was a money-back
guarantee, and in 8 years, the only
refund requested and issued, was
because the poor guy's wife had a
cow over the idea of a beam above
the house. Apparently he failed to
inform her of his plans...

There are thousands of Yagis that beat Raibeams every day. This
proves nothing, just as does the converse.


Perhaps you should argue this with
Dr. Ken Asmus, VA3KA , a scientist who
conducted a shoot-out in Canada...

"The Raibeam RB-36x was installed late fall last year (October '00). For the next few
weeks I used the Raibeam heavily and was extremely pleased with it's performance. In
nearly every comparison with my A4 it was equal or stronger in signal strength. In many
QSO's, both long medium and short range, and on all 3 bands, the RB-36x was 1-2 S units
stronger. This was both surprising and pleasing considering the RB-36x is about 15 feet
lower than the A4. Using the Raibeam I was able to work ALL the major DXpeditions in the
last year (on 20-15-10 meters SSB/CW and RTTY) and was the top Canadian in the 2001 ARRL
DX contest (SSB) 10M single band with 1400 QSO's."

You can see a photograph of the two
towers and beams at:

http://www.raibeam.com/page23.html

The RB-36x has 2 elements for each band,
interlaced on a 14 foot boom, and weighs
only 36 pounds.

I simply published the unsolicited opinions
of others - opinions based on their first-
hand experiences that they wished to
share with others.

Since most gave email addresses, please
feel free to contact those opinionators,
and perhaps you can convince them they
are all delusional, having been brainwashed
by an evil antenna cult leader... g

It proves your fixed opinions are stronger

Tell you what: Steve, ZL1SB is Pat's
neighbor and longtime friend, His email
addy is on my website. Contact him if
you'd like to have your mind opened.

considerable independent testing of this
antenna design and is knowledge of the

It seems inconsistent that you repeatedly

if you bothered to check out the contest
records, it may raise havoc with your
unsubstantiated opinions, perhaps?... hi
