I'm getting Voom installed in a few weeks and I've been reading the information here. I've learned that I should have the installer run 2 cables and not use the diplexer. That leaves wondering me how they run the cables. I currently have TW cable running to all of the major rooms in my house but I will be dropping them and keeping road runner. Do the installers use the existing wiring or do they run new wires to the rooms where Voom wil be? If they run new cable how do they run it since fishing the cables in the wall is extra. I would also like to know if I should expect to see all of my OTA channels before the installer leaves. I've checked and most of the Of the OTA stations are within 10 - 20 miles so I believe that I shoud be able to recieve them. Will I need to wait for some updates before I can see the OTA channels. I don't want to let the installer leave before everything is working as it should.
