Flat transmission line formula

>C/length=4*Pi*e0/(2*Ln((h+sqrt(h^2-a^2))/a))

>Where h is the height above ground of the center of the cylinder and a

Antonio, thanks - I believe the formula you provided will give me what I need.
I appreciate the info!  I will soon post the results of my measurements.
