Hi Mike,
I would recommend to read the notes from Pieter-Tjerk PA3FWM on the MiniWhip.

BTW: Pieter-Tjerk also made improvements to the MiniWhip circuit: http://www.pa3fwm.nl/projects/miniwhip <http://www.pa3fwm.nl/projects/miniwhip>. My understanding is that this design has not been productized, yet. Pieter-Tjerk will not productize it. It’s up to the community to do so.
The WebSDR <http://websdr.ewi.utwente.nl:8901/> at the University of Twente, where Pieter-Tjerk is teaching, uses currently the new circuit with very good results. For this new circuit the same grounding principles as with the PA0RDT MiniWhip apply.

What if I just screwed it on to the side of the house or used a pvc mast. Would I want to run a ground wire up to the bnc connector at the bottom?
