When KFI went to rebuild its destroyed 750 feet tower, the local agencies 
demanded a 10 percent reduction in the physical height of what was 
already an undersized radiator.

750 feet (176 degrees) down to 675 feet (158 degrees).

In order to regain at least the minimum Class A efficiency (the original 
radiator was barely conforming), top loading was proposed, in the form of 
a hexagonal "hat" some 50 feet in diameter, heavily reinforced.

Structural considerations on account of presence of the "hat" meant that 
the radiator cross-section would have to be dramatically greater, eight 
feet as I recall, in order to resist the static and the dynamic loads 
presented by the "hat".

As a greater cross-section actually increases the electrical height, the 
result will be a radiator with an electrical height of slightly over 181 
degrees.

The applicant stated that its intention was to replace the old radiator 
"in kind", and that the new, shorter radiator would be significantly more 
expensive than an "in kind" replacement.
