ITU-R S.465-6 PDF

This Recommendation provides reference radiation patterns that are assumed to be rotationally symmetric about the boresight axis and that, in the absence of particular information concerning the radiation pattern of an earth station antenna, should be used for coordination studies and interference assessment between earth stations in the fixed-satellite service (FSS) and stations of other services sharing the same frequency band as well as coordination studies and interference assessment between systems in the FSS.
