Radar Extension Cable

Hi,
I installed the RD418HD Color Radome Radar. It is the 18 inch radome radar that is HD and color. I need a 5m extension cable for this system to get the radar input to my C97 MFD. I think the extension cable needed for this is the A55080D. Can you verify that this is the proper extension cable for this radar? If this is not the correct cable, could you help me identify the right one?

Thanks for the help,

Gary Green
