This is Peter John with the DX Headlines.
I think I probably talked about magnetic loops in DX Headlines before, which is not strange. It is one of my favorite antenna types because it is so different from other types of antennas.
The most useful property of a pure magnetic loop is most probably the unusual low radiation angle, which is needed for transmitting and receiving over long distances.
For example, most ham radio operators simply haven't got the space to do any meaningful DX on the lower HF bands, and especially not on 160 meters using traditional antennas.
Using a vertical radiator has its own problems, and most horizontal antennas are derived from a dipole or another kind of half-wave radiator.
To achieve a low radiation angle above the horizon, a dipole has to be placed approximately half a wave above the earth, i.e. 20 meters high on 40 meters, 40 meters high on 80 meters, and 80 meters high on 160 meters.
And full-size antennas for these frequencies also are not particularly small. A magnetic loop antenna is such a low radiation angle when placed just above the earth. And for 160 meters, it is only three meters 60, around 12 feet in diameter.
A loop antenna has these advantages, but also has some disadvantages. For example, it has no antenna gain, but rather an antenna loss. When perfectly made, it could give you minus 10 dB compared to a dipole.
So in practice this will probably be even less. In reception however, the lack of gain on 160 meters and lower is not a problem because noise levels are particularly high, so having more gain there wouldn't be of any help.
For the transmitter side within legal limits you can compensate by using a higher output power, but you probably won't need to do so.
With a modest setup like that, it is possible using gray line propagation and being in Europe to work New Zealand on 160 meters in one of the traditional modes, which is almost exactly the opposite side of the globe.
This was Peter John for the DX Headlines on the Mighty KBC.
Hier spricht Peter John mit den
DX-Schlagzeilen.
Ich glaube, ich habe in den DX-Schlagzeilen schon einmal über
Magnetloop-Antennen geschrieben, was nicht verwunderlich ist. Sie gehören zu
meinen Lieblingsantennentypen, weil sie sich so stark von anderen unterscheiden.
Die nützlichste Eigenschaft einer reinen Magnetloop-Antenne ist wahrscheinlich
der ungewöhnlich flache Abstrahlwinkel, der für das Senden und Empfangen über
große Entfernungen notwendig ist.
Beispielsweise fehlt den meisten Funkamateuren schlicht der Platz für sinnvolles
DX auf den unteren Kurzwellenbändern, insbesondere auf
160 Metern, mit herkömmlichen Antennen.
Die Verwendung eines vertikalen Strahlers birgt eigene Probleme, und die meisten
horizontalen Antennen basieren auf einem Dipol oder einem anderen
Halbwellenstrahler.
Um einen flachen Abstrahlwinkel über dem Horizont zu erreichen, muss ein Dipol
etwa eine halbe Wellenlänge über dem Boden angebracht werden, also 20 Meter hoch
auf 40 Metern, 40 Meter hoch auf 80 Metern und 80 Meter hoch auf 160 Metern.
Und auch die Antennen in voller Größe für diese Frequenzen sind nicht gerade
klein. Eine magnetische Rahmenantenne hat einen sehr flachen Abstrahlwinkel,
wenn sie knapp über dem Boden angebracht ist.
Auf 160 Metern beträgt dieser nur
3,60 Meter, bei einem Durchmesser von etwa 3,7 Metern..
Eine Magnetloop-Antenne bietet diese Vorteile, hat aber
auch einige Nachteile. Beispielsweise erzielt sie keinen Antennengewinn, sondern
einen Antennenverlust. Im Idealfall kann sie im Vergleich zu einem Dipol -10 dB
Verlust aufweisen.
In der Praxis dürfte dieser Wert jedoch noch geringer ausfallen. Beim Empfang
ist der fehlende Gewinn auf 160 Metern und darunter jedoch kein Problem, da das
Rauschen dort besonders hoch ist und ein höherer Gewinn keinen Nutzen bringen
würde.
Senderseitig kann man innerhalb der zulässigen Grenzen durch eine höhere
Sendeleistung kompensieren, was aber wahrscheinlich nicht nötig sein wird.
Mit einer solchen einfachen Anlage ist es möglich, mithilfe der
Graulinien-Ausbreitung von Europa aus Neuseeland auf 160 Metern in einer der
traditionellen Betriebsarten zu erreichen – fast genau auf der
gegenüberliegenden Seite der Erde.
Dies war Peter John für die DX-Schlagzeilen auf dem Radiosender
Mighty KBC.
