we have a different brand roof mounted dish but KVH has a good name .... don't know about your luck but for us, if there is a single tree in the CG it will be between us and a clear view of the southern sky .... for that reason it is wise to take along a portable dish, we have found a VuQube serves us well .... no issues with dew or a light rain but just as with our roof mounted dish at home, the signal can be interrupted by a heavy storm .... knowing what I know now, I would not have installed the camper's roof mounted dish but since its there we use it as much as possible
