"John Larkin"

What the carbon-loaded-plastic people are probably doing is diddling
the lossy transmission line equation to add enough shunt loss, the "g"
term, to make the characteristic impedance 8 ohms.

** That is what I said two days ago:

" The conductivity of that graphite layer likely increases the capacitance
per
meter plus add a continuous loss per metre.
It may well do just what the graph shows. "


The result is a
very lossy line. If it were long enough to act like 8 ohms,

** Once again, characteristic impedance is NOT DEPENDANT on the length of
the line.

Absolutely basic stuff.


Characteristic impedance is being confused with impedance. Some people
can't understand the difference.


** Funny how that is what YOU did here - pal.

Deserves an Olympic medal for outstanding backflip.
