The 031-71065: This is the 75 Ohm variant — not the 50 Ohm BNC common in test equipment — so the impedance match is correct for video, broadcast, and CATV distribution where 75 Ohm is the standard line impedance.
This plug is gated to RG-6DS cable — the ferrule ID and centre contact bore match that specific cable's dielectric OD and centre conductor. The contact accepts either crimp or solder termination; the shield termination is crimp, which is the faster method for production harnesses and gives consistent pull-off strength.
