I’m doing an install tomorrow for my father. He has a new Slimline dish that he wants to install at his new house. I do not have the slimline box with me; it’s at his house. It was purchased from Solid Signal. Can anyone tell me if installation hardware is included or if I’m going to need to stop and pick up some supplies on my way? If so, what size lags or screw would you recommend? The dish will be mounted on the roof. Should I purchase a sealant or tar to ensure there will be no leaks? Will the shingles seal around the lags themselves. How important is it to find a beam as opposed to only penetrating the plywood. IF important, is there an easy was to find the beam on a roof, like with a stud finder? Is the extra support bracket included in the box? At this point, I hope so! My dish was professionally installed and it has 2 small arms that attach to the roof in addition to the mast. Is this an extra option or included with the dish? How important is grounding? I’ve read conflicting views. Of the six or so installers that have been at my house over the years, all of them were against grounding. Were they lazy or did they have a point? If I do ground, I know I’ll need an 8 ft grounding rod… can you recommend the type and gauge of grounding cable. It’s about a 25 ft run between where the dish will be mounted and where the grounding rod will be. Sorry for all of the questions! Any advice or suggestions is greatly appreciated! Thanks!
