Roomcap in the
Internet: Read this
many thanks for your request of a technical article or construction guide.
Due to the following happenings, I have them no longer freely available on the Internet.
Since more than 40 years I am experimenting with electronics and antenna constructions.
In 1963 I built my first magnetic loop antenna.
After studying the Maxwell equations I had a new idea in the year 2004.
Based on this idea I built a new antenna in 2005 for the 40m band, of 1.5m length, and
published the results by Packet Radio and in the Internet. Then, I obtained a number of
negative critics from OMs, telling that such good results would not be possible, and that
I would tell ridiculous stories to the HAM radio community.
Disregarding such comments I continued the project, developed new versions and made
comparisons with all other antenna types I had access to. I further published the results,
even so experts with much (and no) antenna experience told me to be a fool.
This remembers me to the story that happened with aviation pioneers. When they tried
their first vehicles, the world was laugthing, and the experts wrote, that this would be a
pure nonsense ... yes, today we know, that a Jumbo with 500 passengers never will be
able to fly, and that the experts told the full truth ... !!!
In the meantime I built this antenna from 10m to 160m, where the radiator of the 160m
version is just 3m long, and all versions are providing incredible good results.
(See home.tiscali.ch/hb9abx/ant--abx-e.htm ).
For the project RoomCap I spent up to now over 1100 hours. If I would calculate this time,
a price would result in an unaffordable amount for radio amateurs. The result of this project
is given under the contract to the interested HAMs worldwide, without covering anything
for my own effort.
In the last time, many critics were written, some from people with EE degree and even
professors of universities (!), where the facts are completely reversed and the arguments totally wrong.
Written by people, who have never seen or having measured this antenna.
All this made me change my position regarding publication of my work.
My technical articles (construction guides and valuable information), which I published since
10 years freely on the Internet are no longer available on my homepage, according to the saying:
Don’t throw your pearls to pigs.
(I write this due to the behaving in the PR mailboxes - and some sysops, who delete permanently all my messages
about my new antenna.)
The technical articles (except RoomCap antenna) are available for sFr.10.- per article.
