How to add new cable or dish wiring into attic
I'm seeing several wires for cable TV that go from the equipment box attached to the brick and run 'around' the house and then enter thru a hole drilled into each room. I'd like to change this and have wires that run 'upward' from the equipment box and enter the attic through the wood siding that is in one of the peaks. I'm thinking there is some sort of plastic box to do this with -- it would look a lot like a dryer vent cap, but would have insulation and holes for each wire to go through, so the water would run off and it would be pretty much bug proof. Do they make such and entry box to the attic for these type wires?
