Conclusion:
This test proves clearly, that the efficiency of the Roomcap Antenna
equals that of large wire antennas,
and hereby confirms the results that I obtained during my own tests
during the last 3 years.
Each operator confirms the logged reports.

The physical explanation of this is, that generation of the EM waves
is done by the dynamic E field, as explained
in "Antennas and Physics". The dominating E field can be measured only
in the near field region of the antenna,
as in the far field a fixed relation between H and E field exists.
The far field does not allow determination how the
wave has been generated originally.

Many thanks to the above mentioned OMs for there voluntary, free
contribution in this antenna test.

Felix , Since you are posting all this in a radio homebrew NG ,could you
please give us all a free reference where to find the details of this
miracle antenna , such that we can build one ourselves.

As noted here you have to sign something and pay to get the construction
guide, you probably sign a non-disclosure agreement so you could be sued if
you published the plans:

Indeed ,he has tried that for the past 2-3 years via the Packet Radio
System . Not very much in the spirit of amateur radio , whereas for
most of his tests Felix uses radio amateurs trying to prove the
effectiveness of his 'invention'.

worse than that, he doesn't tell you what you agree to until you sign
it and receive the antenna.

The fact that its constuction secrets are not all over the internet
speaks volumes. If this were truly a decent antenna there is no way
the genie could be kept in the bottle.

I would have to go with you on this one.

If this design/performance was good many large companies and commercial
interests would have already picked up on it. Indeed, if this were half
of what it claimed, there would be no need to market it to individual
amateurs or use marketing tactics which smack of such secrecy, mystery
and magic--the money from larger users would just make these ideas
laughable.

It seems obvious, if it is marketed like snake-oil, if it comes in a
snake-oil-bottle, if it has the color of snake-oil and ultimately ends
tasting of snake-oil ... it is most likely snake oil--i.e., a lame duck.
(Not even to mention that a partner and I have built a couple! LOL)

However, Barnum and Bailey would be proud!

I have read thru the thread and find nothing that would suggest that
the original poster
cannot do what he states he has done.
By comparing Gaussian law with Maxwell the requirement of his antenna
calls for a system in equilibrium which can be any size ,shape or
elevation. Such a design goes back more than ten years on this
newsgroup when I stated that radiation came in pulses. have described
such as an antenna as one having only distributed loads and where
external lumped loads are imposed during manufacture they must be
cancelled to maintain equilibrium. All of the masters work and
mathematics are based around the requirement of equilibrium law of
Newton i.e addition of all vectors equal zero which is the basis for
no moving charge within a conductor in equilibrium.(this is descibed
in many books or can be googled by inserting current carrying radiator
equilibrium or similar words Root LC in Maxwells equation is
strictly for distributed loads in equilibrium unless the mathematics
have changed in the last 150 yearsand does not include lumped loads as
part of the laws of other masters from whom he got the mathematics
from. If you obtained a helix antenna and lengthened the open end of
the helix by continuing the rotation to the starting point ie
cancelling the lumped loads you have such an antenna that is not
straight and is in a state of equilibrium which provides gain.
Experts, get on Eznec and prove it for yourself, don't just be a
talking head !
There are plenty of programs that can simulate such a arrangement
without difficulty to simulate a small antenna with full wave
dimensions that can provide gains described in his experiments. I have
not seen his antenna and suspect that the addition of chokes are
supplied because he has not fully cancelled lumped load and thus is
trying to prevent feed line radiation which in a lot of cases is not
considered a hindrence.
If the wire used is a wavelength long then you can't stop it radiating
with respect to its unit length if it is in equilibrium. Period. It
is easy to debunk an antenna without reason. It is a lot harder to
find error in the mathematics involved which supports such antennas
especially when it can easily be proved in practice and checked by
anybody. Make it worth my while and I will be happy to prove it
$1000dollar bvet was suggested in the past but with no takers. I only
ask for conpensation for my costs.

By the way, on my page

unwinantennas.com/

I describe how to make an antenna even smaller than that made by the
threads initial poster
I also supplied SWR measurements for frequencies between 2 and 100
Mhz. The wire I used was a random length and the results should be
duplicated with a couple of wavelengths for the lowest frequency.
Isolated spot frequencies can be attained by the use of a jumper. Such
antennas can also be made in small sheet form and other configurations
Wire used for such antennas do not have to be made of wire with
mechanical thickness since no external mechanical stresses are
involved.
Nuff said. I'm gone !

My point can be summed up quickly; where is this antenna being used in
the commercial sector--it has certainly been around to have gained
interest there, if deserved.

That is all folks ...

No such description is to be found on your page,
just utter nonsense.

No, you did not provide measurements, you just depict a few graphs
which you faked.

Mhz. The wire I used was a random length and the results should be

Show one (1) single working prototype.

Interesting statement.
aahahahaaaa....

Yes, sure.
