Summary edit
| Description |
English: Diagram showing rays of the same frequency at several different transmission (and incident) angles. The frequency is greater than the critical frequency, therefore the two most vertical rays pass into space. The next two rays are refracted in the F layer, indicating that the signal frequency is less than the MUF for these angles but greater than the E layer MUF. For the last ray (lowest transmission angle) the E layer MUF is greater than the transmission frequency and the ray is unable to reach the F layer.
Deutsch: Diagramm, das Strahlen der gleichen Frequenz bei mehreren unterschiedlichen Abstrahlwinkeln (und Auftreffwinkeln). Die Frequenz ist größer als die kritische Frequenz, weswegen die zwei steilsten Strahlen ins All passieren. Die nächsten beiden Strahlen werden an der F-Schicht gebrochen, was anzeigt, dass die Signalfrequenz kleiner als die MUF für diese Winkel ist, aber größer als die MUF der E-Schicht. Für den letzten Strahl (kleinster Abstrahlwinkel) ist die E-Schicht MUF größer als die Sendefrequenz und der Strahl kann daher die F-Schicht nicht erreichen. |
