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:

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

"Small - broadband - efficient: pick any two."
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.
