This has been on my project list for some time but I needed to wait until I had most of my switches and the coax jumpers needed. I wanted to mount my coax switches on a board that was not attached to the wall so that it can be removed later without leaving holes in the wall. The board is just sitting on the shelf leaning up against the wall and is being held in place by gravity and all the coax; only the switches are mounted to the board. There is a 1 inch gap behind most of the board because I installed wood strips down both sides of the back and the whole thing was spray painted gray to match the color of the switches.
