Topband: RDF

[Pete Smith]

I have been hunting for more information on RDF, which Tom Rauch defined 
the other day as "the difference between  average gain and gain in the 
desired direction and angle."  I get the concept, but also recall a 
statement that the RDF could readily be computed using NEC-2.  I can't 
figure out how -- can anyone point me in the right direction?
