For most of our purposes, using a 50 or 75 Ohm connector really does
not matter. Look at all the rules that were broken when 10base2 was
popular, especially when people added very short little BNC jumpers,
when the Tee was just a little too tight against the back of the
machine. Somehow the stuff still worked fine.
That's true. Back in my days of 10Base2, I found a great deal on 75 ohm
BNC connectors (the quick-connect, with a threaded hole to secure the
coax cable and braid. RG-58 is a bit too small in its OD for the 75 ohm
BNC connectors. I took some thinwall brass tubing that I had on hand to
make up the difference in cable size, soldered the braid to it and
threaded the result into the connector.
It worked just fine with no apparent shortcomings. I think I still have
a length of the cable with said connectors somewhere...
