I also installed a pole in the ground for the DirecTV dish. When a winter storm hits and the dish ices over, I can get it de-iced with a pitcher of warm water. That works a lot better than putting the dish on the roof.
The dish is right outside my bedroom window, so it kinda works the same for me :)
Besides, most of the storms through here are all snow, because they generally throw a bunch of ice into columbus.
They had installed a grounding block on the side of my house and it seriously looked horrible. What we did is we took the coax straight down into the ground (we installed a 2 foot L-section of PVC in the ground and ran it behind the wall in my rec room into the basement, where we then wired everything from the ground up.
Works great.
