Jim, if what you are saying is the case, then yes, I agree.

I would add that I am pretty sure that a lower band parasitic vertical 
array (an inverted L is a top loaded vert in reality) needs a VERY 
EXCELLENT ground to work right.  And that means a pretty limited amount 
of metals in the field as well.  A few radials off to one side is 
definitely not going to make a guy smile much in the end.

If that's literally the only option, then investing a lot more in 
getting radial concentration around the vert is needed.  And in the 
worst case, driving the pair using phasing lines and forgoing the 
parasitic plan.
