Doug, >From what I have found, RG-21A/U cable is 53 ohm impedance, 0.339" outer diameter, double silver-plated copper braid shields, and a solid center conductor of "high resistance wire." The dielectric is solid polyethylene, and the jacket is black PVC. If you have a sample of this wire, please reveal what is printed lengthwise on the jacket.
