Well i had 2 Hoppers/2 Joeys installed today. They seemed pretty insistent that we at least get the hoppers on properly rated cable. I wasn't going to argue and we kind of came up with a plan to only use the home distribution for the joeys.
A combination of my knowledge sourced from this forum and the tech's experience, my install was taken care of with new Channelmaster 3ghz rated RG6 hopper runs.
We basically swapped some room locations between the two hoppers and two joeys that i wanted. Basically the hoppers moved to rooms that were closer to the dish and allowed them to minimize running too much wire on the siding.
There were already three existing satellite lines that went inside to the home distribution where the old DPP44 switch was located so that took care of all the joeys. We basically placed the node where these three lines penetrated the house as it was a pretty concealed location behind the air conditioning. Then ran two new lines outside to the closest rooms to that node so that as little visible wire was run as possible to the hopper locations.
For right now i'm not messing with my setup by doing any experimenting, so that puts off any of my initial worries about reusing 20+ year old RG6 for now. However when OTA is ready, i may move a hopper to a room that has an antenna run to the attic. Basically what i can do is use that extra line that's going to the home distribution for a hopper and connect it up.
For me, this was the better play although i supervised the heck out of the wall penetrations and they measured a few times to make sure it was done perfect. In the long run, i'll now have extra runs of that old RG6 from the home distribution to those same hopper locations. That should work out nicely for mirroring purposes (in the event i need to cut costs).
