I see Mr Carlson and others using BNC connectors for projects and connecting up to test equipment. I’ve never used BNC style connectors and am getting confused looking at the options. Does anyone have any go to connectors they use?
Simply depends on the application.
Chassis mount are for chassis
Depending on what cable your installing the male connector on, depends on the connector.
Not sure I understand your question fully?

BNCs are most commonly found on late model oscilloscopes for the sorts of standard test probe leads. Prior they used other coax connectors but often simple banana plug connections. Be aware there are two characteristic impedances for BNCs, those used in video signal work & those for RF, video being 75Ω & RF being 50Ω respectively. An oscilloscope will tend to use 50Ω. They are quite the universal connector when it comes to connecting a coaxial cable to a circuit & their variations is quite large. There are even sockets that detect a connection has been made so a built in mechanical switch trips another circuit. Most cable ends are terminated quickly with a crimp method however spanner up types are also available.
If you go to sites like Mouser, Newark, or Grainger and look at bnc connectors you may also get more general knowledge. Pasternack also is a company that makes custom cables and has a lot of info on BNC connectors.
Here are two BNC connectors available thru MOUSER:

Any time I restore an old-school signal generator or other test gear, I always replace the Switchcraft-type connectors with BNC’s
@peteb2 Your avatar pic made me do a double-take – reminds me a lot of Bob Pease. 😀
@dtidrow That’s the biggest compliment i have ever had! When i was a much younger technician back in the 1990s starting out back in New Zealand having been on my OE (overseas experience) working in the UK for Hitachi, i looked forward ever month to Bob’s “What’s All This…. Stuff, Anyhow”? dissertations in Electronic Design Magazine. Bob Pease was certainly a quirky gentleman but he had an incredible ability to depart his knowledge in a manner that kept the reader involved & i always learned so much & it made me think!. I was actually stunned when i learned he’d passed so suddenly. I still have many of his writings as .pdfs.
@peteb2 TI has put a bunch of old videos of his up on YouTube… perhaps a bit dated now, but still well worth watching, especially for those of us still working with analog electronics.
@dtidrow May i ask for a link to these TI videos please? I have searched on the YT page but it’s not coming up… As to BNC connects i must have over they years crimped a few 100 thousand onto cables, being a tech in a TV Station, at least it feels like that. They were all 75Ω because it was composite video which later became SDi (serial digital). I’ve terminated a few 50Ω RF spanner-up BNCs for radio antenna installs but that was mostly hobby time stuff. I was thinking the other day about the Robot machine my employer would hire whenever a big install happened back in the 1980s that would auto-prep the end of the coax perfectly so you just slide the centre pin on the inner conductor, crimped it followed by the BNC body & crimped it. The Robot was very special & they cost in excess of $1million at the time!!! I continue to use BNCs as they are so convenient at home in my DIY projects now i am almost retired. I built a switchable dummy load for working on HiFi amps & added a couple BNCs chassis mounts so i can patch direct to the ‘scope for testing.
@peteb2 Here’s a playlist I found: https://www.youtube.com/playlist?list=PLMKxBlyAyypxuaI7pbfRkSryvTDef_Y1S
A bunch came up just by putting “Bob Pease” in the YouTube search bar, but the playlist above would definitely be a good start. 🙂
