A recent experiment by Antonini et al. [Phys. Rev. A 71, 050101 (2005)] set new limits on Lorentz violating parameters in the framework of the photon sector of the standard model extension, {kappa}-tilde{sub e-}{sup ZZ}, and the Robertson-Mansouri-Sexl framework, {beta}-{delta}-1/2. The experiment had significant systematic effects caused by the rotation of the apparatus which was only partly analyzed and taken into account. We show that this is insufficient to put a bound on {kappa}-tilde{sub e-}{sup ZZ}, and that the bound on {beta}-{delta}-1/2 represents a fivefold, not tenfold, improvement as claimed.
