Homer, here is my belated response to this issue you posted above long ago. I must have missed it, because I always had similar results with my real Sigma 4. The match was always close with a good SWR, but the values of R & X were always off a bit and I never saw near a perfect match while tuning. However, the Z value on my VA1 analyzer typically showed 50 ohms match across the CB band.

I use to explain that as the complex value for the impedance when I was asked what the Z value was.
