Bayonet Neill-Concelman connectors, or BNC connectors, are popular in pro-video and some audio applications. BNC connectors are for coaxial cable and can be found on video routers, amateur radio antenna connectors, electronic test equipment and more. Here are some things to look for when you buy BNC adapters.
Instructions
1. Learn the difference between the male and female BNC connectors. The difference between the male and female ends of BNC connectors is not as straight forward as other connectors and it is essential to know the difference when buying adapters. The male end is the larger end and has a coaxial pin in the middle. The female BNC connector has a hole in the center for the coaxial pin. The male BNC connector has the locking mechanism that connects to the female end.
2. Try a BNC to RCA adapter to use BNC only commercial video equipment on RCA consumer electronics. The adapter is affordable and it will make your life easier if you do lots of video work. The adapter should have a female BNC connector on one side and a male RCA on the other. You can also find male BNC to female RCA adapters, so be sure you know which you need.
3. Buy a BNC "T" adapter to split a signal using BNC connectors. You can find BNC "T" adapters that have 3 male ends, 3 female ends or a combination of male and female BNC connectors. You can also find right-angle BNC adapters that can make it easier to connect hard-to-reach BNC connectors.
4. Find BNC adapters for other connectors like banana plugs, N connectors, Motorola connectors and more.
5. Make sure you are getting a BNC adapter that is the right ohm rating for what you need. BNC connectors come in 50- and 75-ohm versions. It should say on the connector which ohm version it is. You can also check for dielectric material around the inside of the male end of the connector, which often designates a 50-ohm connector, whereas a lack of dielectric material signifies a 75-ohm connector.
