G3LDR made one as a roof rack many years ago; designed for 20m as I recall.

That's not really true.  The DDRR is NOT a loop antenna.  The DDRR is a very 
short vertical with top loading contributed by a shorted transmission line 
(formed by the horizontal loop and the ground plane).  Check the field 
polarization ....

Hi Gary,

  Seems to me that you are right on with all but the very last part... and 
that may need some investigation, with relation to the DDRR antenna.. that 
is a loop, and horizontal, over a very good ground. Just a thought....
