Speaker Wire Balun Test

FT140-61 15 turn

AIM 4170D Measurement

SimSmith Model

SimSmith N-Block Schematic

Loss Measurement

Measurement frequency = 14 MHz
Measured Balun output = 40.9 -> ((40.9 + 0.25)/(2)^.5)^2 / 200 = 4.23 W
Measured DL1=10.2 -> (10.2 + 0.25)^2 / 25 = 4.37 W
Difference=0.14 dB
