Sorry for the voice over. Had some issues with the wireless mic but I didn’t want to waste the video.
Sealing the hole left behind from the screws are very important. They make roofing tar for a caulking gun. You’ll be able to purchase this in any home store. A little tab is all you need. Spread it around a little is all you need.
And trust me. I’ve had satellite dish TV before and as long as it’s mounted correctly with no obstructions and really heavy cloud cover they work just great. My personal opinion I like the satellite much better than the cable companies.
