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.
