High sensitivity 21-cm H I line observations with an rms noise level of similar to 0.5 mJy were made of 35 spiral galaxies in the Coma Supercluster, using the refurbished Arecibo telescope, leading to detection of 25 objects. These data, combined with the measurements available in the literature, provide the set of H I data for 94% of all late-type galaxies in the Coma Supercluster with an apparent photographic magnitude m(p) <= 15.7 mag. We confirm that the typical scale of H I deficiency around the Coma cluster is 2 Mpc, i.e. one virial radius. Comparing the H I mass function (HIMF) of cluster with non-cluster members of the Coma Supercluster we detected a shortage of high Hi mass galaxies among cluster members that can be attributed to the pattern of H I deficiency found in rich clusters.
