I think all three cables are coaxial.
I think the large one is the main antenna feed for the radio (AM) from the module in the roof spoiler area.
The two smaller coaxes (one black and one white) are the diversity antenna cables from the rear and/or side windows - for the FZV and FM radio.
Not 100% sure on all the actual sources/destnations - but pretty sure they are all coaxial.... and therefore will require coaxial connector to repair (most likely).
You have both ends, right? Or have you removed the other half of those looms...?
*edit* - ok - that's a triple!!
