See remarks on post "Guanella balun 1 core versus 2 separated cores".
Return loss measurement:

Left: FT 240-43 Right: FT140-43


Insertion loss measurement:



The measured loss is for two devices. Divide the result by two, to see the loss value of one device.
0,10 dB means that you have a power loss of 2,3 %.
