Interesting, Mark, although your SWR decreases really aren't that significant, in my opinion, and might be due to some sort of interaction with your increased grounds.
But, I hasten to add that I'm far from an exxpert on this stuff. So, take my thoughts here with a grain of salt, because they probably aren't worth much more than that! (LOL)

Hi
Here is my analysis of grounding a dipole. When I had my dipole up with out a ground at the station or the antenna, the SWR was 1.5 at MHz 7.191 I installed a station ground and the SWR went to 1.4. I then connected the antenna to a second ground rod, and the SWR dropped to 1.2.
Thus, the old theory about dipoles being self contained, needing no grounding just doesn't hold water with me.
Just my personal experience.
God bless,
REV. Mark

Perhaps I'm old-fashioned and possibly out of date Tom, but I would whack in that eight foot rod and tie everything in to it.
