Hi, I have an HR34 scheduled to be installed this weekend, and due to a previous hack job that was done on my prior home by the D* contractor some years ago, I prefer to have all of my rg6 in place myself so they are not tempted to destroy anything to add cabling. Currently, i have 3 rg6 from an existing mast that run into the attic (old E* install) and a single rg6 from the attic to the LR where the HR34 is needed. This is the only box i am getting for now, so I am wondering if this is enough, or will I need an additional rg6 from the attic to the LR? I am guessing that the 3 from the mast to the attic should be enough for that run?
