The example in Kraus showed isotropic radiators, but the same zero
sidelobe, infinite F/B descriptors for the array pattern apply for any
pattern shape generated by the individual radiators, as long as
they are the same.

I need to correct myself. As applying to binomially-fed FM broadcast
arrays I should have written infinite max-min ratio, not infinite F/B ratio.
