Antenna Theory:

There are many textbooks telling that an antenna
to be effcient needs "much wire in the air".
Now the time has come to correct this view.

This new view is based on many practical tests
on all HF bands over a year.
As en example read the email below.

The antenna used for this contact was 3 meters
long and 1.5 m above ground. (= RoomCap Antenna)
The contact was on the 160m band over a
distance of 600 Km.

Hallo Felix,

nach unserem tollen QSO auf 160m waren
Peter (DL1BLD) und ich (Heino, DJ5ER) total
erstaunt mit welch einer tollen Feldstaerke Du
in Bremen angekommen bist.
Wie man eine solche Antenne bauen kann
moechten wir gerne wissen (auch fuer die
anderen KW-Baender).

Hello Felix,

after our fantastic QSO on 160m we (Peter,DL1BLD)
and I (Heino, DJ5ER) we were completely surprised
with what a strong field strength you arrived in Bremen.
We would like to know how such an antenna can
be built (also for the other HF bands).

Heino will receive the construction guide.
