Results of H166\alpha recombination line observations from the Outer Galaxy in both the Northern and Southern Galactic Plane, are reported. The Southern observations were made with the 30m antenna of the Instituto Argentino de Radioastronomia in Villa Elisa, Buenos Aires, Argentina and the Northern ones ( more sensitive, high quality observations, performed with an "state of the art" receiver) with the 43m antenna of the National Radio Astronomy Observatory, in Green Bank, West Virginia, USA. From the two sets of observations, we obtain evidence of the warp of the low density ionized gas layer, traced by the H166\alpha emission in the outer MIlky Way, towards positive galactic latitudes in the Northern and towards negative latitudes in the Southern Galaxy. The warp of this tracer qualitatively agrees with that of the HI.
