Hi Andreas,

A feed through should have no damping (0dB).

 Both ways can be used. For low inductance of a current shunt let the return wire go close to and in parallel with the shunt resistor to minimize any area for the magnetic field.





 I have ordered the 50 Ohm coax cable and a couple of shunts. I just found my 50 Ohm feed throughs. It’s a set of 4 pieces, 3dB, 6dB, 10dB and 20dB. I am note quite sure which one to use and how they behave differently!?
 

 Thanks a lot,
 

  Andreas
