Who is the "they" in this post? I looked all through this post and 
quoted stuff to find "them." If you're referring to mfrs, what makes you 
think they use NEC for design? There are multiple modeling programs.

It's easy enough to produce an EZNEC file for an antenna that doesn't 
include inductors or capacitors -- all you need a a measuring tape and a 
caliper to determine element diameters. In his very useful 
self-published "Array of Light," N6BT includes detailed descriptions of 
many  Force 12 antennas he designed for the company he owned.
