Hello, I am planning to install an additional cable TV outlet on the opposite side of a wall that already has Coaxial cable running up through the floor directly next to the wall. Instead of having to drill a series of holes through the wall studs (the new location is on the opposite side of the wall and on the other end) to run the wiring, I would like to add a splitter underneath the house (double wide manufactured home) and then drill a hole through the floor insulation and through the subfloor and bottom plate of the wall into the wall cavity (in the area I want the outlet to be) and then cut an hole in the drywall to install a cable TV outlet. What is the best way to drill through the insulation and bottom plate? I've heard that Flex bits and Glow rods are typically used in these kind of applications, but I personally don't have any experience using them. I would like to avoid twisting the insulation into cotton candy and creating an large air gap if possible. The space below the house is only a crawlspace unfortunately. Any suggestions are appreciated! Thanks.
