Antenna matching
E' - examples for FM and AM
E' = reference point (output of matching device/dummy antenna
without load) in dBµV.
Y = adjustment of the signal generator in dBµV or µV.
V = attenuation of the signal generator output due to the load applied
by the matching device (power adaptation).
X = attenuation of the dummy antenna in dB.
D
Antennenanpassung
E' - Beispiele bei FM und AM
E' = Bezugspunkt (unbelasteter Ausgang der Anpaßschaltung/
künstliche Antenne) in dBµV.
Y = Meßsendereinstellung in dBµV oder µV.
V = Meßsenderbedämpfung durch die Eingangsimpedanz der
Anpaßschaltung (Leistungsanpassung).
X = Dämpfung der künstlichen Antenne in dB.
Y = V + X + E'
(X =14 dB) Y = 6 dB + 14 dB + 40 dBµV
Y = 60 dBµV = 1 mV
(X =20 dB) Y = 6 dB + 20 dB + 40 dBµV
Y = 66 dBµV = 2 mV
Y = V + E'
Y = 6 dB + 40 dBµV
Y = 46 dBµV = 200 µV
V = 6 dB
