Notes
Opened: The Poppler documentation states: “Returns to the user whether this node should be expanded by default. The document may provide an indication of how the document's index should initially be expanded. “Text: Note that the text is output as it is found in a particular rectangle - as shown in the snippet in the following example:
Die Experimente zur Bestimmung des Stehwellen-Verhältnisses (SWR) wurden auf einem kommerziellen Messplatz an der Kaiser-Max-Universität in Heidelburg durchgeführt. Die Antennenhöhe betrug 11,3 m. Die Leistung wurde auf 10 W Ausgangsleistung begrenzt. Folgende Antennen für den Amateur-Funk wurden untersucht: * Richtantenne FB33 (3-Element-Beam für das 20m-Band, 15m-Band und das 10m-Band) * 2-Element-Monoband-Yagi für das 20m-Band * 2-Element-Monoband-Loop für das 20m-Band Auswertung: Bei allen drei Amateurfunk-Antennen konnten die in den Datenblättern angegebenen Werte hinreichend bestätigt werden. Das bezieht sich jedoch nur auf die Größe des SWR. Abweichungen gab es bei der Lage der Minima im Frequenz-Band.
