Topband: Impedance of two wires to ground?

[Michael James <mrscience65704@yahoo.com>]

Hello,

I'm looking for the formula to calculate the surge impedance of two wires 
parallel to the ground, given the diameter of the wires, the wire spacing, and 
height above ground.

I know I've seen the formula in a textbook in my library some years ago, but 
I'll be darned if I can find it.


I'm fairly new to the topband list, and I'm impressed. I don't see the usual 
bickering and personal attacks common elsewhere. If 160 meters is the 
"Gentleman's band", then this is the 'gentleman's list'.

TIA and 73,
Mike W0BTU
