Buy and enclosed satellite dish if you put a roof mount, with 4 or 5 years my dish would not stay locked on to satellite if was in the least bit windy out, called manufacturer and was told "that's what happens, it needs rebuilt" after experiencing that and the fact that you have to choose campsites based on trees and other things in your line of sight for satellite reception I bought a tripod mount HD dish off amazon for $100 bucks or so and can set it up anywhere, fasten it down good and no problems. just my opinion.
