Etienne,

It appears that your radome cable is a Light Analog Radome Cable rather than one of the Heavy Analog Radome Cables specified for use with 4kW radomes. The Heavy Radome Cable was specified to ensure that sufficient power is supplied to 4kW radomes and was accomplished by constructing the Heavy Radome Cables and Extensions with an additional set of power leads. Accordingly, the 4D 4kW radome features two pairs of power terminal to accommodate the Heavy Radome Cable's four power leads. Before abandoning your Light Radome Cable, it has been my experience that these cables are often satisfactory if the cable length is relatively short (ex. radome is installed on a powerboat). Accordingly, it is recommended that you evaluate the performance of the radome using your Light Analog Radome Cable and if found to not supply sufficient power to the radome, that it be replaced with one of the Heavy Analog Radome Cables listed within the FAQ found here. To connect the power leads of the light cable to the 4D 4kW radome's power terminals, you may connect the cable's heavy gauge red lead to either positive (+) terminal of the radome core. Similarly, the cable's heavy gauge black lead will be connected to either negative (-) terminal of the radome core.

Should the MFD's Radar application report "Scanner Not Responding" or "Checking HW", then please note that these reports may indicate the insufficient power is being supplied to the radome and that you may need a Heavy Analog Radome cable.
