I'd put the antenna, or at least the short, on a separate layer, in the
same group as the normal copper layer.  For verification, you can
temporarily move the antenna layer to it's own group.  Just remember to
do the checkout with the correct group assignment.  If you get an extra
gerber layer for the short, then you know you made a mistake.
