To begin I am in a bedroom with wood floor then thick carpeting. The walls are drywall. There is also a floor board around the room. I have a coax cable coming up through the floor in the center (not a corner). I will get a wall plate and mount without a box but with inserts. That is how I want too...no giant holes! Under the room is my garage with a dry wall ceiling. In the corner is the main meeting place of coaxials. It goes to the cieling where a 6" by 6" square was cut away. It goes up to the bedroom there. The hole isn't directly below where it comes up though. About one foot off. Up inside is a place I prefer not to stick my hand in too much. It *is full of insulation. I can get a cutter and new tips if needed but what is the best way. Pull old cable out? Will I run into studs between the levels?
