That impedance is set by the PTFE dielectric and the centre-contact geometry, and it matches RG-179 class cables. A 50 Ohm BNC on this cable would create a mismatch; the 031-70339 is the correct 75 Ohm plug for that cable group."},{"question":"What cable is compatible with Amphenol 031-70339?","answer":"RG-179, 179A, 179B, 187, 187A, and Belden 9221.
