Hi... I would ask those with experience to critique what I am proposing to do to ground my satellite dish and rg6 cables (I am doing my own self install)... What I propose to do is the following... In the attic, just inside the place where I poke a hole in the house to bring in the four video cables from the triple lnb/5x4 multiswitch, I intend to mount a quad ground block. Those four video cables from the multi-switch outputs will attach to 4 high bandwidth barrels that are part of that ground block. Then four other video cables will attach to the other side of those barrels and will go on to where I will have receivers in various rooms. I will then run a #10 wire from the base of the satellite mast (outside) to this ground block (just on the inside, in the attic). I will then run another #10 wire from that ground block, through the attic and down into the garage where I can bond it to the service ground where it comes into the house.
Does this sound ok or is it flawed?? If so, how?? Also, if you ground the shields as I have described above at or near the place where those cables enter the house from the outside, and if you also ground the shields a second time at the receiver inputs which I am assuming are also grounded through the ground of the receiver chassis, does this cause issues with ground loops??? I am an EE and work with signal conditioning systems all the time where we endeavor to only ground shields at one end, at one place, to avoid ground loops... But it appears from everything I have read that because of NEC codes and safety concerns, grounding at the house point of entry is a must... Are the receiver ends also grounded as I am assuming??? I am not buying receivers until I get everything else bought and figured out, thus my ignorance of how the receivers are configured though I did read recently that they ARE grounded, at least the newer ones are.... So any comments about ground loops and whether or not they are a problem in these satellite setups??
One last quick question, why don't they allow the shields of the four multi-switch outputs to be connected to a ground lug right there rather than forcing one to install these grounding blocks some distance away, the latter of which forces a barrel connection in the middle of the video feed, something that I would assume can only cause signal loss and problems. Grounding right at the start of those video cables would remove the need for that extra barrel connection... My guess is the answer is NEC code rules about grounding right at the penetration point but perhaps someone can clarify??...
