IITU-T Recommendation K.71 provides information to network operators on when antennas may be installed in, or on, a customer building without performing a building-specific risk assessment. When a risk assessment is required, the Recommendation provides guidance on the application of IEC 62305-2. It also provides information on the responsibilities of the network operator and the building owner. This revised version of Recommendation K.71 has updated references and added definitions from IEC 60364-5-54 to minimise confusion regarding protective conductors. The section on protecting against contacts between the antenna and feeder cable has been amended. Appendix II has been checked to ensure the generic risk assessments are in line with IEC 62305-2 ed. 2
