Fifty-seven radio sources in the directions of clusters of galaxies were observed with the VLA with resolutions of approx.1-4''. Thirty-eight narrow angle tail (NAT) sources from these observations were combined with 13 from the literature to produce a representative sample of 51 NATs in the directions of Abell clusters. The global properties of this sample were investigated. Correlations between various parameters (i.e., optical rank, core and total power, width, length, galaxy velocity, distance from the cluster center, cluster richness, Bautz-Morgan type and Rood-Sastry type) were examined and discussed within the context of our current understanding of rich clusters of galaxies. The statistical results are in agreement with the hypothesis that the tailed morphology of these objects is due to the interaction of the radio plasma ejected by the moving galaxy with the intracluster medium.
