Just for information. When Dish upgraded me to the Hoppers they replaced all the cable (and DISH) from the dish to the Duo node with the 3ghz RG6. To each of the hoppers they refused to use any of my existing wiring which is also RG6 (but not marked 3ghz) and also lower loss, fatter Quad Shield RG-6. So I gave up and had them run new cable to 2 Hoppers.
One of which is in my Family room and is ok.
The other I just told them to put it in the damn Den even though I wanted it to replace the 622 which was in in the Master BedRoom. So they ran that cable, were nicely smug and satisfied, but I was not, and they left.
The next day I moved the Hopper that was in the Den to the MBR using the RG-6 Quad Shield cable and it works perfectly including all the single strengths on all tuners including Tuner 3. I then swapped cables and put the Joey that they put in the MBR in the Den in now the over configured Den new RG-6.
So yes, Hoppers will run just fine as long as the run from the dish to the node is the newer cable. I'd make a bet I could also use the other cable in the wall which is the regular RG-6 and bet the Hopper will also run just fine. But it's running on the Quad Shield so I now have it configured the way I originally wanted it.
