While you are entirely correct that there are 75 ohm and 50 ohm BNCs, 
the difference DOES NOT MATTER at HF, because the connector is such a 
small fraction of a wavelength and the difference is small. 75 ohm 
connectors were important with analog video because of the smearing of 
very fine detail in a high res image, and because studios do lots of 
patching and routing.
