Do gravity waves radiate equally in all directions?

If so, is this an inherent property of all gravitational waves or is it just due to how they are normally produced? In other words, in a theoretical scenario, could we have gravitational waves that don't radiate isotropically?

If they do not, in a theoretical scenario, could gravitational waves that radiate isotropically exist?
