Topband: Impedance of two wires to ground?

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
