Correct. There is no TV in this location right now and or will be in the near future. In looking at a couple of mounted ones I have in the house right now, all Chief mounts....48 seems to be a good general compromise on location on height.....unless I do tilt, pull (in which I would mount the TV higher due to how it will be used/seen).
I've got the HDMI, coax, network drops all pulled already in the same location.
Just debating where to cut that hole ;-)
