Sorry Bob, I could study it a bit and maybe make a wild guess. What do you think it means?

 

When I originally read this I thought it might have something to do with the 3/4 wave ground plane antenna with horizontal radials vs. one with the radials raised up. That is what happens with my Eznec models. Zt looks to be at the base, and Za looks to be higher up in the image and I thought maybe that was referring to the gamma circuit maybe.
