OK.  I understand what you are saying now.  But I think a more accurate 
way to describe it would be to say minimum reactance (obviously zero 
reactance is a minimum).  If you have a fixed antenna and a fixed length 
of feedline and are tuning around looking for a dip, that dip may or may 
not occur at a point of zero reactance but I would guess it certainly 
would occur at a point of minimum reactance.

True.
