BNC is fine. SMA is probably more common in this application, but BNC is widely available, and easier to swap around than SMA. Since this is receive-only and the pigtail will be short, coax loss isn't a real concern either — you probably want to choose something fairly thin and flexible to minimize the stress on the fragile MCX connector.

BNC work well, make a positive connection, and are simple to crimp. I would suggest that you purchase a pigtail rather than manufacturing one because the SMA connectors are a beast to crimp. As far as the cables themselves, provided they are still in good shape, both RG-58 used by 10Base2 and RG-8 used by 10Base5 are 50 ohm impedance coax, which is exactly ...

The Anderson power pole connectors I had to dismantle were not easy to disassemble by hand. (They were not glued, nor did they have a roll pin.) Using the instructions provided by this website (black goes forward, red goes backwards), I set the bottom of the black connector on top of the edge of a table with the red connector hanging off the table ...

The question asked about separating the plastic parts of a PowerPole connector with more than one conductor. Other answers talk about this. If you want to further break apart the connectors, follow the text below. It is actually fairly easy. Prepare connectors - slide them apart, if not already, and get a paperclip, or something similarly strong and thin ...

The origin of this connector is Kenwood. We work with Kenwood and build custom headsets for Kenwood. This link is pretty much up to date and definative. https://www.wildtalk.com/knowledge-base/kenwood-2-pin-wiring-data/ The 5V pin has varied over time. Initially this was via a 100 ohm limiting resistor to provide power to an external VOX unit. More recent ...

FWIW: The Baofeng UV-5R HT supplies 3.3V through 100(*) ohms on the tip of the 3.5mm connector, not 5V as documented above. Also, the PTT is pulled up thru 10K to 3.3V, and the MIC+ connection line also has a more complex (constant current source?) pullup to 3.3V. [This is nice, as the PTT line can directly connect to a Raspberry Pi GPIO pin!] There's a (...

Either find an adapter that will work or cut the end off the RG-8 and solder on the proper connector. You could also find an SMA cable and replace the RG-8 entirely.

I wouldn't say that SMA is "the" standard RF coaxial connector, I would say that it is one standard among many. No connector has emerged as the best for all uses, which is why there are many standards. Other connectors such as the "UHF" (badly-named because its performance is terrible at UHF), BNC, F, and N connectors were invented ...
