 The HF system is composed of:
 -
two transceivers

 -
two antenna couplers

 -a shunt-type antenna. The antenna is common for the two HF systems.

 The HF system is associated with:
 -
the Radio Management Panels (RMP) which are centralized systems enabling the frequency display of the HF system (Ref. ATA 23-13)

 -
the Audio Management Unit (AMU) for connection to the audio integrating and SELCAL systems (Ref. ATA 23-51)

 -
the Centralized Fault Display Interface Unit (CFDIU) (through the MCDU) which is a centralized maintenance system (Ref. ATA 31-32)
