  We report the measurement of the flux-averaged antineutrino neutral current
elastic scattering cross section ($d\sigma_{\bar \nu N \rightarrow \bar \nu
N}/dQ^{2}$) on CH$_{2}$ by the MiniBooNE experiment using the largest sample of
antineutrino neutral current elastic candidate events ever collected. The ratio
of the antineutrino to neutrino neutral current elastic scattering cross
sections and a ratio of antineutrino neutral current elastic to antineutrino
charged current quasi elastic cross section is also presented.
