Default folded dipole calculator help

Your statement:
The fellow I'm disagreeing with say's,
"the reason that the variable in the calculator for the "dipole feed
impedance"
could be if you want to transform the z to something else, such as 50 ohms."
I don't even understand what he means.

My thoughts: My radio output impedance is 50 ohms, for a feed line I use
RG-8 and other 50 ohm impedenance coax.
If I were to use a folded dipole antenna I think I would prefer one that had
a 50 ohm feedpoint.

Ya no doubt we all want a match.
I don't think you looked at the calculator.
I think he wants to put 50 into the data input line labeled
Simple Dipole Feed Impedance (Ohms)

and thinks it somehow affects the folded dipole.
I think it is just a number that is multiplied by the
calculated ratio.
