For my Gen4, then Gen5 upgrade, they used the same coax that was installed back in my original install in 2004, the only difference being they used one leg instead of both. They installed new connectors for the Gen4 upgrade, and they installed new connectors again for the Gen5 upgrade, plus a new fuse block.
The same pole has been used since the beginning for mine, even though it's nowhere near regulation. It's too short, but being there isn't really any other easy place to put it, there being no children around here and me being perfectly fine with using the same one, they did. They just repointed the dish and changed the polarization on the radio (or whatever it is they change the polarization on).
