I did much the same, with one added feature. I didn't trust the drip loops and 
driving West Texas rains, (when we do finally get rain), so I made the drill 
through at a slight downward angle to the outside. I know, after you seal it, it 
shouldn't matter. I used some DAP I had from a bathroom project for the seal, 
easily removable, (the landlord allowed a 2nd antenna later). Guess it was like 
chicken soup, made me feel better. :-)
