For video
applications, you need a 75 Ohm plug. Almost all other
appications (test equipment, ethernet) use 50 Ohm.
Sounds a little off. Cables are important, with impedance
varying with diameter, _Terminators_ are important, coming
in the 50, 75 Ohm varieties mentioned, but the connector
itself being 50 or 75 Ohm? First I've heard of this.
The connector rear half can come in sizes to match the cable
OD, that's about it by my understanding. A mechanical, not
electrical difference.

important? probably not. thread drift? probably!
