    PROS: Works great; Lightning quick
    CONS: None specified
    We ended up getting these as a replacement for a similar part we had gotten. The collet on these is thicker, and the connector doesn't pull straight off the cable like our other part sometimes did. Great piece at a reasonable price!

Q: What does BNC stand for?

A: BNC stands for Bayonet Neill-Concelman. They are named after the bayonet locking mechanism and their inventors.

Q: What are BNC connectors commonly used for?

A: BNC connections are typically used on RF, video and ethernet applications.

Q: How can I tell the difference between a 75 ohm and 50 ohm BNC connector?

A: On a 50 ohm connector the center pin is surrounded by a white dialectric. On a 75 ohm BNC connector is surrounded by air (no dialectric)

Q: Can a 50 ohm and 75 ohm BNC connector be connected together?

A: 50 ohm and 75 ohm BNC connectors will mate with each other. At frequencies under 10 MHz the impedance mismatch will not have any affect. If you are above 10 MHz the chances of signal distortion becomes more significant.
