Introduced: January 2015
Full Title
Full titles differ between systems:
IPC:
Arrangements for simultaneous operation of antennas on two or more different wavebands, e.g. dual-band or multi-band arrangements > Arrangements for providing operation on different wavebands
CPC:
Arrangements for simultaneous operation of antennas on two or more different wavebands, e.g. dual-band or multi-band arrangements (combinations of separate active antenna units operating in different wavebands and connected to a common feeder system H01Q21/30) > Arrangements for providing operation on different wavebands
IPC and CPC are identically structured here. All 2 subcodes exist in both systems.
IPC defines codes here since 2015.
