"Fider loss input 0.5dB"
#atu-100
Hello Roby,
You can configure the loss of the feeder line (cable loss) from the ATU to the antenna. See the documentation of configuration cell 34: "34 ¡ª cell for setting a feeder power loss ratio, the first number ¡ª integer part of?
decibell, second number ¡ª ten¡¯s parts of decibell. Velue by default ¡ª 1.2 (12 writen?
in the cell). this value uses for counting the power delivered to antenna. The loss?
value can be found in the reference data for the used cable or you can measure the exact value yourself.
?If it is not necessary to take into account feeder losses, the value 00 should be
written into the cell, then the calculations will correspond only to the mismatch
losses." 73, Joerg - DB2OO |
Hallo Joerg,
Ich habe nach Immo's mail ([email protected]) auch ins Manual geschaut und folgendes ihm geschrieben: Hallo Immo, Meine Firmware ist 3.2. Ich glaube aber Joerg lag falsch. Es ging da eher um folgenden Punkt (original Text englisch manual): 33 ¡ª cell for setting of an addidional indication mode, value 00 ¡ª for indicating L and C only. value 01 ¡ª for indicating the power delivered to the antenna and efficiency of fider and transmitter §áwhen input power is enough for correct SWR meassuring. By default is enable, value 01. Warning!!! The device does not take into account its own efficiency. Aber ich nehme an auch hierbei handelt es sich um kein eigentliches Problem. ? Vielen Dank nochmals f¨¹r eure Hilfe! 73, Roby? |
