2PCS SDI Connector BNC Adapter 75 Ohm BNC Female to Female Barrel Connector for HD-SDI/3G-SDI/4K/8K SDI Video Camera Cable

Works great!

Perfect for when your coax stretcher is not available. Sometimes, no matter how many times I cut a section of coax, it's still too short. Handy to have on the shelf because eventually you'll need it! They don't seem to degrade the performance of my aviation band transceiver.

This BNC Female to Female Barrel Connector 2-pack is an inexpensive way to extend BNC type video cables by connecting 2 (or more) cables together rather than having to go out and buy a longer cable.

I needed a few extra 75 ohm, 12G capable barrel connectors so figured I'd give these a try. While the ability of a true 75 ohm, 12G compatible device to pass a clean signal is more noticeable on longer runs of cable, I only have short (~18") 12G cables, so my experience is relegated to only these shorter runs.Setting my camera to send out a 4K signal to my 4K monitor, these barrels worked just fine. I got a clean feed and, even when wiggling them to test the connection, never lost picture or saw any artifacts. So for my purposes, these do exactly what I wanted them to do.You might ask why these are about $6.50 per barrel when there are tons of way cheaper SDI connectors out there. If you look closely, the lower priced ones are generally all 50 ohm, 3G barrels, which aren't designed for 6G or 12G signals, so are more likely to give a degraded signal or fail to pass a signal at all. So if being able to pass 4K video over any substantial length of cable is important, spring for these higher end connectors.

BNC barrel connectors are a dime a dozen, but actual 75 ohm-rated connectors require a teflon insulator like this is advertised as having.These should work with any RG6 with minimal loss. Cheap, non-rated connectors linking long runs will have more loss for SDI and this can cause loss of the digital signal.These connectors should not be used for long 50 ohm applications.

Once in a while you need to run your SDI cabling a little further than your cable - and these little adapters work very well to run them end-to-end. Upon use, there was no struggle to connect the cabling. It all fit well and tightly and carried the signal very well. These are a great product to have around!

Needed to add a length of BNC cable to cross the attic. Saw these and knew they were what I needed. Solid fit, No burrs. The camera worked after the connection. As it should.

Needed for security camera extension on home security system. Perfect fit with good connection and signal strength.
