  We compactify the abelian 6d (1,0) tensor multiplet on a circle bundle, thus
reducing the theory down to 5d SYM while keeping all the KK modes. This abelian
classical field theory, when interpreted suitably, has a nonlocal
superconformal symmetry. Furthermore, a nonabelian generalization, where all
the KK modes are kept, is possible for the nonlocal superconformal symmetry,
whereas for the local superconformal symmetry we can only realize a subgroup.
