We had our satellie installed 19 months ago,..Lost signal on one of the tvs..call for repair...they found that the cable on the lnb was totally off...the satelitte is on our roof, so I know nobody messed with it.. Is this a common occurence or was the wrong type of cable used or could it be that it wasnt screwed on right to begin with? I live in a trailer park and all satelittes are facing in the same direction. We all get the same wind and rain, But it seems that we are the only people out here that had this problem. Would appreciate an answer to this problem...thanks
