In this talk we present a sharp bilinear inequality for the Klein-Gordon propagator for dimensions d > 1, in the spirit of earlier work done by Carneiro for the Schrodinger propagator, and Bez-Rogers for the wave propagator. From this inequality we obtain a sharp Strichartz estimate for the solution to the Klein-Gordon equation in the case d = 5, and that there are no maximising functions (that is, functions for which one has equality) for this estimate. We also recover a recent result of Quilodran concerning the closely related Fourier restriction problem for the hyperboloid. Finally, we comment briefly on the case d = 1, and describe some open questions.
