[TenTec] NEC, ground, grounds, and radials.

Jerry,

I can understand that the interpretation of dBi which appears in most 
engineering texts (and possibly the IEEE definition?) throws up 
conundrums with which you are uncomfortable. But what I think is unfair 
is to claim that EZNEC is in error, simply because it adopts the 
"industry standard" interpretation rather than an alternative that you 
might prefer.

I make widespread use of EZNEC, and when I saw someone as authoritative 
as yourself state that it is 3dB in error I felt it needed further 
investigation!
