Although the formulae did not copy properly, if one wants to help me with
this, they can go to the link below for the proper fomatting of these
formulae. I would really appreciate it.

Thank you.

j/b


d= .0808 (12 gauge stranded copper)
S= 6 inches
r=Effective dielectric constant (Air = 1.00054)


Here is the Wikipedia link for these formulae:

The formula to calculate the impedance of ladder line is:





The formula to calculate the impedance of open (air dielectric) ladder
line
is:



The formula to calculate the distance between conductors of open ladder
line
is:



Whe
Z0 = Impedance.
S = Center to center distance between wires.
d = Diameter of the wire.
r = Effective dielectric constant (Air = 1.00054).
The unit of measure for S and d are not critical as long as they are the
same.

I GET DIFFERENT RESULTS WHEN COMPARING TO A GRAPH.
