It is shown that there are two equivalent field potentials for massless spin-2 fields in (3,2)--de Sitter space; a symmetric two-tensor and a three-tensor of mixed symmetry. Each theory carries two inequivalent Gupta--Bleuler triplets, which correspond to the two helicities. They differ in their behavior at spatial infinity. All four fields appear when writing linear conformal gravity in de Sitter space. Two of them describe the unitary conformal gravitons, and two describe part of the conformal ghost.
