A common style of BNC connector is ___.

• A. liquidtight connector
• B. modular connector
• C. none of these
• D. compression connector

Answer: (D)

BNC connectors can be terminated in a few different styles, but in many professional installations the compression style is the go-to choice because it gives a solid, field-terminable connection without soldering and with good RF performance. The compression method uses a ferrule and sleeve that are tightened onto the coax, creating a tight grip on the shield and a precise alignment of the center conductor, which helps maintain the connector’s impedance and minimizes signal loss or reflections. This makes it reliable, durable, and weather-resistant for many video and RF applications. The other options don’t apply to coaxial BNC terminations—liquidtight connectors are for conduit fittings, modular connectors are for telecom/networking jacks, and “none of these” isn’t correct because a compression BNC is indeed a common style.
