Not really true: antechamber respects the atom names in the input pdb file.

I suspect that your pdb file had atom names in the wrong columns, so that
several atoms ended up with the same name (as read by antechamber). In that
case (and that case only) antechamber will disambiguate the names by adding
numbers after that input name.

Aside: not at all sure whay using atom names is "dumb". In any event (as
Hannes notes) it is a common practice in many codes.
