The original cable box is on the garage wall, outside. So, I'm sure the installer will use it again. I can punch a hole right there, and be in my garage. Can then route anything I need into the attic and then anywhere in any wall in the house.
I'm DIY, person - but my daughter's husband is an electrician - so I can get his help when the times comes.
My main question was - do I need something more inside the house - so I can ask if that is part of the service install, if not, then I'll just do it.
From what I understand here, it probably needs some upgrades inside, so will see what the service installer does as his part. Then I will know. Once they finish, if no work is included inside, then I will add whatever cables I need. Thanks for the advice guys ... M 44 :)
