The UJC does not supply attenuators. When required, these are to be supplied by the cable manufacturer or system supplier. The UJ Consortium does not take responsibility for the long-term reliability of any third-party supplied attenuators that may be installed in the UJ. Any attenuator to be installed in a UJ requires prior confirmation, by the UJ Consortium design authority who has qualified the cable type, that the attenuator can be physically accommodated within the UJ.
