Roomcap experience … frustration and success
Tiado, DL9PB intended to build a Roomcap antenna. His first tries were
frustrating and he
began to doubt ...
On January 14th, 2011 he wrote me the following e-mail:
(translated from German)
here I am again. My vacation is over and I had to work this week.
Now I just found some time to test again the Roomcap. Now I even could
hiss the antenne above the roof,
however, it is not working at all as I desired. Will dismantel the
antenna and begin with the 40m Roomcap version.
So far I built the 20-30-40m version with a movable aluminium foil.
I just tested with a station in Saarbrücken.
Using a 10m long wire directly from the transceiver without coax, and
tuned with the internal tuner of my
Yaesu equipment I got a report of 9+ from the other side. When using
the Roomcap I only received a S 5.
There must be something wrong ...
Now it is raining. Maybe water in the antenna ? I don't know ...
You know, I ordered 2mm dia copper wire instead the 1.5 mm dia. Does
this change anything for the
40m monoband version ?
Best regards and have a nice weekend
I answered him and was asking some
specific questions. Then, several mails were sent back
and forth, as some misinterpretations did exist. Today, January 29th, I received from
Tiado the following e-mail:
invention is really fantastic. Today I have been qrv on 40 m.
A contact with London. After that my QSO partners have seen the antenna
in QRZ.COM, they
can't beleave it. 9+20 in London. Other stations with much larger
antennas and more power had
the same reports, or only 9+.
Also when calling USA I was always successfull.
Before, using my dipole, I had problems to hear
at least something from there. I am very delighted and I am advertizing
it by telling, they
just have to
look in Google, where they find all about it ...
advantage I note is, that this antenna receives less noise. The
frequency is much more clear.
That's all for now. I just had to get rid of this message.
I think, this is a really interesting experience, Tiado
Don't you think so ?
