  We study a large extra dimension model with active and sterile Dirac
neutrinos. The sterile neutrino masses stem from compactification of an extra
dimension with radius $R$ and are chosen to have masses around eV or keV, in
order to explain short-baseline anomalies or act as warm dark matter
candidates. We study the effect of the sterile neutrino Kaluza-Klein tower in
short-baseline oscillation experiments and in the beta spectrum as measurable
by KATRIN-like experiments.
