Impedance of corrugated coaxial cable

Please login with a confirmed email address before reporting spam

I need assistance in calculating outer conductor dimensions for a 50 ohm coaxial cable.
center conductor = .188" copper clad aluminum
Vp = .94
there are 7 peaks in 1.211"
we need .040" corrugation depth
what would the peak and valley measurement need to be if .015" thick copper is used as the material for the outer conductor ?
