Yeah, that's similar to what I did at my last house. Ran the big fat coax down to a first floor window, where I layed a 2x4 with a hole drilled in it across the bottom of the window frame. I just put silicone around the coax after it fed through the hole, as well as weather stripping the top, bottom, and sides of the 2x4. I had those little window security clamps on the window so it could not be raised from the outside. It's no less secure than any other single pane window that can be easily broken anyhow.
