If it's mounted outside you have what Hoppy mentioned, as well as Lightning arresting, proper grounding, drip loops, weather sealing of connections, proper routing of wires, Not drilling through the wall and hitting an electrical wire, ETC. Having lightening hit it and light your house on fire, having water in your wall, or electrocution while you drill through the wall are probably things you want to avoid..
I have years of experience with electrical installations. I was just worried that I might be missing something RF wise. I would hate to set this thing up and give someone butt cancer because I had the gain set to high.
