Currently I have a 3LNB dish mounted to the framing on the side of my roof as pictured below. When I upgrade to the 5LNB larger dish will this type of support bear the weight of the dish (notice only 3 of the lags are being used on the current mount). In any case the line of sight is not a concern as we are located in a rural area on a hill with no trees around the property. Please advise of my potential mounting options.
