Default reciprocity and program zl_zin ??

Thanks,

Can you explain "transmission performance". Is it as measured and the source,
Zin? What is the range of Reflection Coeff? Is it a percentage? Is refl. coeff.
angle measured at Input?

Thanks, Dan

Is there a program that will calculate Zin from a known Zload?


==========================================

Yes, from the same place you obtained program ZL_ZIN.

For coax lines use program COAXPAIR.
For balanced twin lines use programs RJELINE3 or 4.

These programs are to professional standards, 1% accuracy or better,
covering the frequency range from audio to UHF.
