Belden already tests three of its cables to to 4.5 GHz to cover 1080p/60. (Clock is 1.5GHz, 3rd harmonic is 4.5GHz.) They are 1694A, 1505A, and 1855A and each is printed that they are tested to 4.5 GHz. Return loss maximum on all three cables is -23 dB (5MHz-1.6 GHz) and -21 dB (1.6GHz-4.5GHz). So anyone who wants to run single cable 1080p/60 can do so, at least from the cable side. The really interesting part is what we had to do to get these three cables to pass this extended spec: absolutely nothing, except change the number on the print legend. They are all passing without any manufacturing changes. This means that any of our 3 GHz versions will also pass 4.5GHz. If it doesn't, we'll replace it free. So we over-engineer yet another product. We're very sorry that we gave you more than you paid for. We'll try not to do it again! We spent bucks to get new test gear to go to 4.5 GHz at 75 ohms (not standard products). As far as I know, we're the only manufacturer in the world who can now test to 4.5 GHz at 75 ohm. So where's the 1080p/60 equipment??? ************************************** See what's free at http://www.aol.com.
