    Hello,
    I am quite new to circuit simulations. I wanted to estimate Insertion loss for the twisted pair cable and modelled it as seen in the schematics attached to the post. Please, could somebody give feedback for this simulation! Something seems wrong to me in my configuration

      It looks fine to me. If you are worried about the ripple in
      transmission, try changing your ports to 100 ohms, which is closer to
      the TEM impedance of the line. It looks smooth with about 2 dB of
      insertion loss at 100 MHz under those conditions.
