The real difference between the two impedances is that the amount of
PTFE dielectric in the 75 has been minimised in order to increase (with
some difficulty) the Zo from 50 to 75 ohms. IIRC, the 50 has a
more-uniform structural RLR, so it the better connector at the higher
frequencies.
I don't think that's quite right. The diameter of the inner and outer
conductors has more influence on Zo than the dilectric thickness.
