Are you looking for equations for impedance? (There's the one equation.. 
Z is approximately 276*log(ratio of diameter to spacing.  There's a 
formula involving cosh(x) that is more exact. )
http://www.rfcafe.com/references/electrical/transmission-lines.htm has 
lots of other configurations

  Construction details?

Usage?
