So I kept my Winegard TOGO because it is a half decent WIFI extender, and serves as an internet backup. I want to roof mount it because I'm sick of it living on top of my cabinet. But I noticed that the plastic SIM cover has no gasket. It just screws over the area.

For those that have them, is that normal? How well does it actually protect that area from the elements? I'm asking because over the last 2 years I've seen my fair share of snow and horizontal rain. Anyone ever have one of these things get water in them and fry the boards?
