Abstract: If $ H \circlebin{s} K$ is a semidirect product such that the automorphisms of $ K$ induced by $ H$ are inner automorphisms, $ H$ has equal uniformities and $ K$ is compact, then $ H \circlebin{s} K$ has equal uniformities. Other closely related results are obtained and used to give an alternate proof that a semidirect product $ V \circlebin{s} K$ of a vector group and a compact group is isomorphic to the direct product $ V \times K$.
