Re: NEC-LIST: Significance of ?/10 segments in dipole design

A number of the NEC front end/wrapper programs (like 4nec2) implement a
function which scans your input deck against these kinds of guidelines. Kind
of nice, especially if you're scaling a model originally designed for
something else (like changing a HF beam to UHF, and forgetting to change the
element diameters)
