Folks first of all I'm an HT integrator. ISF/HAA certification and more! With the advent of new UHD footage, I've had issues with HDMI cables. A lot of people say they will be broadcasting UHD signals, but that's not true; Many say they are 18Gbps, but they are NOT. I was looking for an extension cord [seems MANY of my customers are ordering the wrong lengths OR the wrong cords]. Everyone seems to want to mind their own business these days. In short, I need 18Gb/s EXTENDER with 4K bandwidth. I am very happy to announce that YOUR CABLES are up and running! End of the story. Many Thanks. bob walter
