BNC to UHF Adapter ShiverPeaks 98811 — Video/Audio Coupling Adapter

The BNC to UHF Adapter ShiverPeaks 98811 is a passive coupling adapter designed to connect devices with male BNC video or audio connectors to equipment with female UHF (SO-239/PL) ports. It provides a straightforward mechanical and electrical link for signal routing between professional video/audio equipment and radio frequency devices without requiring active components or power. The adapter is compact and suitable for temporary conversions, test setups and field interconnections where BNC and UHF terminations must be joined.

Advantages

This adapter offers a simple, low-profile solution for joining BNC and UHF terminations while maintaining the expected coaxial connection geometry. Its passive design ensures no additional signal processing or power is required, and the mechanical coupling is suitable for short-term and diagnostic use. The adapter is compatible with common BNC male plugs and female UHF sockets, making it versatile for mixed audio/video and RF environments where matching connector types is necessary.

Suitable for

• Temporary signal conversions between BNC-equipped video/audio devices and UHF-equipped receivers or transceivers
• On-site testing and troubleshooting of coaxial signal paths
• Field interconnections in broadcast, production and radio setups
• Situations requiring quick adaptation between BNC and UHF connectors without re-cabling

Key specifications

• Connector A: BNC (male)
• Connector B: UHF / SO-239 (female)
• Type: Passive coupling adapter (no active electronics)
• Application: Coaxial signal conversion for video, audio and RF paths
• Construction: Metal shell with threaded UHF coupling for secure mechanical connection

How to use

Insert the male BNC plug into the adapter’s BNC socket until it locks with the bayonet twist, then screw the adapter onto the female UHF port until the threaded coupling is hand-tight. Ensure connections are secure but avoid excessive force on the threads. The adapter does not require configuration or power and can be added or removed as needed during testing or temporary setups. Use appropriate cable strain relief and support to prevent undue stress on connectors during prolonged use.

Recommendations

For reliable performance, use this adapter for temporary or diagnostic connections rather than as a permanent installation. Keep the mating surfaces clean and protected from moisture and corrosive environments. When handling RF signals or professional AV chains, verify impedance and signal compatibility to avoid mismatches that can affect signal quality.
