No, it assumes a radiator of conventional uniform cross-section, about 3 
feet.

Sure, as one would expect of a radiator with a very large uniform 
cross-section, about 9 feet.


Physical height may be of significance to tower erectors and to the FAA, 
but whenever I use the term "height", I always mean electrical height, 
and nothing else, unless otherwise qualified.
