Thanks Six Shooter, I found the specs for a square/rectangle DDRR in a book by Peter Dodd, G3LDO (silent key). It was his second edition, "The Antenna Experimenter's Guide" copyrighted 1991.

I have to do some more work on this model, because the book shows the antenna specs at 14 MHz. I scaled the model up to 27.205 MHz, but I want to try making the ground plane resemble closer to a mobile roof line.

I'll be posting this model in a new thread.

So, I'm hoping to finally see one of my DDRR models produce some significant vertical polarization...like The DB described above as possible.
