New cable tv receptacle

[jmart273]

I'm tired of running my satellite cable through my slide seals and want to install a new exterior cable receptacle on the outside.

I have a great location to do it. My question is what should I be worried about with drilling a hole on the outside of my unit? After looking around online, it looks like these units don't come with screws, or any sealant.

Is there enough "meat" to screw into the side of the unit?

What screws should I use? How do I seal it so it doesn't leak? Thanks for the help!
