I'm having an upgraded dish installed next week and I'm unsure as to how it should be grounded. My current dish is a roof mount near the middle of my house. The coax runs along the roof and down the west side of the house. It is grounded to a gounding rod on the west side before entering the house. The new dish will be a roof mount using a non penetrating roof mount near the east side of the house. The dish is being relocated due to neighbor's trees. With the non penetrating mount, the cables will go through the roof instead of over the roof. The cables will ultimately wind up in my utility room on the west side of the house via the basement ceiling. As I see it my options are as follows: 1) Connect the cables to a new grounding block in the utility room and ground to my main water supply. (Is this a problem that the cables are not grounded before entering the house?) 2) Run the new cables through the west exterior wall and connect to the existing grounding block on the outside. (Not my first choice since I don't really want more cables on my siding.) Your thoughts are appreciated!
