run a wire down a story and a half to a ground rod
As the Radioworks article points out, that is an "unground" and may be the
worst thing you can do. The story and a half is almost exactly a quarter wave
on 20 meters meaning you will see a high impendence at the radio end. Other
bands will also offer significant mismatch ca suing the energy to stay on
your rig.
When I had a second floor shack I used no ground at all. I ran my coax away
from the antenna at a right angle or straight down to the ground, then back
up again at the shack end to minimize interaction with the antenna field. I
also used a choke balun at the radio end. That cured my problems.
