Okay.
I got the dimensions adjusted to specs, and then I made a new Gamma Match.
I felt the old one wasn't handling this antenna properly, so I made a bigger/beefier one.
The new Gamma is a virtual copy of the old dimensions, with exceptions as noted below:
tube -------- 5/8" diameter x 17" long (as opposed to 1/2" x 17")
rod --------- 1/2" diameter x 30" long (as opposed to 3/8" x 33")
I also made a new dog bone/strap from 1/8" x 3/4" aluminum flat bar with the tube to rod centers length @ 6" (as opposed to 5.25").
The Gamma Rod length is pulled out from the tip of the rod back to the sleeve tube top 23". The Dog Bone is set
from the bottom radials bracket up the Vertical Radiator to a distance of 33".
I put the MFJ-259b on the antenna with the E1/2ƛ jumper and measured for with the antenna tower standing in the air and feed point at 27.5" height these results:
I then went into the shack with the coax feedline back on the antenna and with the analyzer measured the results from there:
"Feelin' so much betta"
