Abstract: The spectrum and propagation losses of a surface magnetostatic wave in a 1D ferrite magnon crystal are experimentally studied as a function of angle $\varphi$ between the wavevectors of the surface magnetostatic wave and periodic crystal lattice. Variation in the positions of Bragg forbidden bands with angle $\varphi$ is described. A wide transmission band is discovered near long-wave frequency boundary $f_0$ of the surface magnetostatic wave in a narrow interval of angles around $\varphi\approx$ 57$^\circ$. In the interval 70$^\circ<\varphi< 90^\circ$ and at frequencies below $f_0$, there exists a magnetostatic wave with a wavevector that is normal to the bias field.
