TUK Ltd BNC Coupler - 75 Ohm, 12GHz

This coupler is designed for professional AV and broadcast applications requiring reliable, high-quality connections for Ultra High Definition (UHD) and 4K video signals, such as SDI.

While it can pass analog signals, its true 75 Ohm impedance and design are optimized for high-frequency digital signals like SDI (up to 12GHz).

Yes, this is a female-to-female coupler designed to join two male BNC cables together, effectively extending the cable run.

'True 75 Ohm' ensures proper impedance matching, which is critical for preventing signal reflections and maintaining signal integrity, especially at high frequencies used in 4K and UHD video.

Use a specialized BNC connector cleaning tool or a lint-free cloth lightly dampened with isopropyl alcohol. Ensure connectors are completely dry before re-connecting cables.

No, this coupler is specifically designed for coaxial video signals (BNC) and is not suitable for networking data like Ethernet.

It conforms to broadcast standards SMPTE424M and ST2, indicating its suitability for professional video transmission.

Ensure both BNC cables are securely and fully connected to the coupler. Verify that the cables themselves are not damaged and are true 75 Ohm. Check that the source and display devices are functioning correctly and set to the appropriate input/resolution.

Confirm that the coupler is functioning correctly and that the connected cables are of high quality and properly terminated. Clean the BNC connectors on the cables and the coupler. Ensure the signal source is stable and not introducing noise.

Check that the keystone opening is a standard size and not damaged. Ensure no obstructions are preventing the coupler from seating fully. Gently apply even pressure around the edges of the coupler until it clicks into place.
